    Physics

    Foundation
    What happens to the boiling point of water at high altitude?

    It falls

    Boiling happens when vapour pressure equals the surrounding air pressure. Less air above you means less pressure to overcome, so water boils cooler — which is why food takes longer to cook up a mountain.

    Foundation
    Which travels faster through water than through air?

    Sound

    Sound is a pressure wave and moves faster through denser, stiffer media — roughly 1,480 m/s in water against 343 m/s in air. Light does the opposite: it slows in water.

    Intermediate
    Why does a spinning ice skater speed up when they pull their arms in?

    Angular momentum is conserved

    Angular momentum is the product of rotational inertia and angular velocity. Pulling the arms in cuts the inertia, so the rotation rate must rise to keep the product constant.

    Intermediate
    What is the primary reason the sky is blue?

    Rayleigh scattering of shorter wavelengths

    Air molecules scatter short wavelengths far more strongly than long ones — the effect scales as the inverse fourth power of wavelength. Violet scatters even more than blue, but our eyes are much less sensitive to it.

    Advanced
    In special relativity, what happens to a moving clock as measured by a stationary observer?

    It runs slower

    Time dilation. The effect is real and measured routinely — GPS satellites would drift by about 38 microseconds a day without correcting for it, which is tens of kilometres of positional error.

    Advanced
    What does the second law of thermodynamics say about entropy in an isolated system?

    It never decreases

    Entropy in an isolated system never decreases. It can stay constant in a reversible process, which is an idealisation no real process achieves.

    Foundation
    Which of these is not a form of electromagnetic radiation?

    Sound waves

    Sound is a mechanical wave needing a medium. Electromagnetic radiation is oscillating electric and magnetic fields and travels through vacuum — which is why space is silent but not dark.

    Chemistry

    Foundation
    What is the most abundant gas in Earth’s atmosphere?

    Nitrogen

    Nitrogen is about 78% by volume, oxygen about 21%. Argon is a distant third at under 1%, and carbon dioxide is around 0.04% — small, and consequential out of all proportion to its share.

    Foundation
    What does a pH of 7 indicate?

    Neutral

    pH 7 is neutral at 25°C, where hydrogen and hydroxide ion concentrations are equal. The neutral point shifts with temperature — pure water at 50°C is neutral at about pH 6.6.

    Intermediate
    Why is water a liquid at room temperature when similar-sized molecules are gases?

    Hydrogen bonding between molecules

    Hydrogen bonds are unusually strong intermolecular forces. Without them water would boil around −80°C, and the planet would look nothing like it does.

    Intermediate
    What distinguishes an isotope from a different element?

    Different number of neutrons

    Protons define the element. Isotopes of an element share proton count and differ in neutrons, which changes mass and stability but barely touches chemistry.

    Advanced
    What is a catalyst’s effect on a chemical reaction?

    It lowers the activation energy

    A catalyst provides a lower-energy path, speeding both forward and reverse reactions equally. It reaches equilibrium faster without moving where equilibrium lies.

    Advanced
    Why do noble gases rarely form compounds?

    Their outer electron shells are full

    A filled valence shell leaves little to gain from bonding. "Rarely" is doing real work though — xenon forms several stable compounds, the first of which was made in 1962.

    Biology

    Foundation
    Where does photosynthesis take place in a plant cell?

    Chloroplast

    Chloroplasts contain chlorophyll and the machinery for both the light reactions and the Calvin cycle. Like mitochondria, they carry their own DNA — a relic of having once been free-living bacteria.

    Foundation
    What is the function of red blood cells?

    Carrying oxygen

    Haemoglobin binds oxygen in the lungs and releases it in tissues. Mammalian red blood cells eject their nucleus during development, freeing space for more haemoglobin.

    Intermediate
    What does DNA replication being "semi-conservative" mean?

    Each new molecule keeps one original strand

    The double helix separates and each strand templates a new partner, so every daughter molecule is one old strand and one new. The Meselson-Stahl experiment that showed this is often called the most beautiful experiment in biology.

    Intermediate
    Why do antibiotics not work against viral infections?

    Viruses lack the cellular structures antibiotics target

    Antibiotics attack bacterial features — cell walls, bacterial ribosomes, bacterial enzymes. Viruses have none of these and replicate using your own cells, leaving nothing for the drug to act on.

    Advanced
    What is the role of tRNA in protein synthesis?

    Brings amino acids to the ribosome

    Each tRNA carries one amino acid and an anticodon matching a codon on the mRNA. It is the physical adaptor that turns a nucleic-acid sequence into an amino-acid sequence.

    Advanced
    What does "natural selection acts on phenotypes, not genotypes" mean?

    Selection sees the organism, not the underlying DNA

    Survival and reproduction depend on traits as expressed. Genotype matters entirely for what is inherited, but selection can only act on what it can see — which is why recessive alleles persist while hidden.

    Foundation
    What do mitochondria produce?

    ATP

    Mitochondria generate ATP through oxidative phosphorylation. A typical cell recycles its entire ATP pool many times a minute — the molecule is a currency, not a store.

    Astronomy

    Foundation
    Why does the Moon always show the same face to Earth?

    It is tidally locked

    Tidal locking: the Moon rotates exactly once per orbit. Tidal forces dissipated its original spin over time, an outcome common throughout the solar system.

    Foundation
    What causes the seasons on Earth?

    The tilt of Earth’s axis

    The 23.4° axial tilt changes how directly sunlight strikes each hemisphere. Earth is actually closest to the Sun in early January, during the northern winter.

    Intermediate
    What is a light-year a measure of?

    Distance

    It is the distance light travels in a year — about 9.46 trillion kilometres. The name is unhelpful, which is why astronomers mostly use parsecs.

    Intermediate
    What will eventually happen to the Sun?

    It will become a red giant, then a white dwarf

    The Sun is far too light for a supernova. In roughly five billion years it will expand into a red giant, shed its outer layers, and leave a white dwarf slowly cooling.

    Advanced
    What does redshift in the light from distant galaxies indicate?

    They are moving away from us

    Wavelengths stretch as space between us expands. Hubble’s observation that redshift scales with distance is the observational foundation of the expanding universe.

    Advanced
    Why can nothing escape from inside a black hole’s event horizon?

    Escape velocity exceeds the speed of light

    The event horizon is where escape velocity reaches light speed. Since nothing travels faster, nothing gets out — no exotic physics required, just the same escape-velocity idea taken to its limit.

    Earth science

    Foundation
    What causes earthquakes?

    Sudden movement along faults

    Stress accumulates along a fault until friction is overcome and the rock slips suddenly, radiating the stored elastic energy as seismic waves.

    Foundation
    What is the greenhouse effect?

    Atmospheric gases absorbing outgoing infrared radiation

    Greenhouse gases are transparent to incoming visible light and absorb outgoing infrared, warming the lower atmosphere. Without any greenhouse effect Earth’s surface would average around −18°C.

    Intermediate
    How are most of the world’s great mountain ranges formed?

    Collision of tectonic plates

    Continental collision crumples crust upward — the Himalayas are still rising as India pushes into Asia. Volcanoes build individual peaks, not long ranges.

    Intermediate
    What drives ocean currents at the surface?

    Prevailing winds and Earth’s rotation

    Wind drives surface currents, deflected by the Coriolis effect into the great ocean gyres. Deep circulation is driven instead by density differences from temperature and salinity.

    Advanced
    What does radiometric dating measure?

    Decay of unstable isotopes

    Radioactive isotopes decay at fixed rates, so the ratio of parent to daughter isotope acts as a clock. Different isotope pairs suit different timescales — carbon-14 for tens of thousands of years, uranium-lead for billions.
