Every sheet in October 1954
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st October 1954Describe, in terms of wavelength, the difference between the radiation the Earth receives from the Sun and the radiation it re-emits from its surface.
- 2nd October 1954What happens to the energy described as 'wasted' in a transfer?
- 3rd October 1954State what happens to the internal energy of a substance as it is heated, in terms of the kinetic and potential energy of its particles.
- 4th October 1954Explain the difference between irradiation and contamination.
- 5th October 1954A radio wave has a wavelength of 3 m. Calculate its frequency, given that all electromagnetic waves travel at 3 x 10^8 m/s in a vacuum.
- 6th October 1954Explain why electricity is transmitted through the National Grid at a very high voltage rather than at the voltage used in homes.
- 7th October 1954A microscope has a x10 eyepiece lens and a x20 objective lens. Calculate the total magnification.
- 8th October 1954Name the products of protein digestion.
- 9th October 1954State the difference between an antibiotic and a painkiller.
- 10th October 1954Name the chemical released at a synapse that carries the signal across the gap.
- 11th October 1954Explain why deforestation to create land for cattle grazing can reduce biodiversity.
- 12th October 1954Explain why potable water is not the same as pure water.
- 13th October 1954Explain why sodium chloride conducts electricity when molten but not when solid.
- 14th October 1954Convert 250 cubic centimetres into cubic decimetres.
- 15th October 1954A student heats solid copper carbonate strongly in a test tube, and it breaks down into copper oxide and carbon dioxide. Heating must be continued throughout the reaction for it to keep going. State whether this thermal decomposition reaction is exothermic or endothermic, and explain your reasoning.
- 16th October 1954State two products, other than water, that can be formed during the incomplete combustion of a hydrocarbon.
- 17th October 1954Write the formula for calculating an Rf value.

- 19th October 1954What happens to the total resistance when a second resistor is added in parallel, and why?
- 20th October 1954What happens inside the nucleus when a beta particle is emitted?
- 21st October 1954Explain why a larger vehicle mass increases braking distance.
- 22nd October 1954State the type of force that always acts between an induced magnet and the magnet that induced it.
- 23rd October 1954Name the model of the origin of the universe that is supported by red-shift observations.
- 24th October 1954State three factors that increase the rate of diffusion.
- 25th October 1954Explain 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.
- 26th October 1954Define oxygen debt.
- 27th October 1954Explain one benefit of the Human Genome Project.
- 28th October 1954What does 'concordant' mean when applied to titres?
- 29th October 1954What did the alpha scattering experiment show that the plum pudding model could not explain?
- 30th October 1954Magnesium is burned in an open crucible and the mass increases. Explain why.
- 31st October 1954Explain why solid sodium chloride does not conduct electricity, but molten sodium chloride does.
