Every sheet in March 1964
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st March 1964State the two substances that must both be present for iron to rust.
- 2nd March 1964State the size range of a nanoparticle.
- 3rd March 1964Why is aluminium extracted by electrolysis rather than by reduction with carbon?
- 4th March 1964Explain, using collision theory, why increasing the concentration of a reactant in solution increases the rate of a reaction.
- 5th March 1964State what happens to the carbon-to-carbon double bond of an alkene monomer during addition polymerisation.
- 6th March 1964Describe, in terms of wavelength, the difference between the radiation the Earth receives from the Sun and the radiation it re-emits from its surface.
- 7th March 1964What happens to the energy described as 'wasted' in a transfer?
- 8th March 1964State what happens to the internal energy of a substance as it is heated, in terms of the kinetic and potential energy of its particles.
- 9th March 1964Explain the difference between irradiation and contamination.
- 10th March 1964Name the type of electromagnetic wave used to sterilise medical equipment.
- 11th March 1964A transformer has a primary current of 2.0 A and a primary voltage of 230 V. The secondary voltage is 460 V. Assuming the transformer is 100 percent efficient, calculate the secondary current.
- 12th March 1964A microscope has a x10 eyepiece lens and a x20 objective lens. Calculate the total magnification.
- 13th March 1964Name the products of protein digestion.
- 14th March 1964State the difference between an antibiotic and a painkiller.
- 15th March 1964Explain why reflex responses are faster than voluntary responses.
- 16th March 1964Define community, in ecological terms.
- 17th March 1964Explain why potable water is not the same as pure water.
- 18th March 1964Explain why sodium chloride conducts electricity when molten but not when solid.
- 19th March 1964Convert 250 cubic centimetres into cubic decimetres.
- 20th March 1964A student heats solid copper carbonate strongly in a test tube, and it breaks down into copper oxide and carbon dioxide.

- 25th March 1964What happens inside the nucleus when a beta particle is emitted?
- 26th March 1964Explain, using Newton's Third Law, why a swimmer is able to push themselves forward by pushing backward against the water.

- 28th March 1964State what red-shift shows about the motion of most distant galaxies.
- 29th March 1964State three factors that increase the rate of diffusion.
- 30th March 1964Explain why a small number of healthy volunteers are given a very low dose of a new drug in the first stage of a clinical trial.
- 31st March 1964State the word equation for aerobic respiration.
