Every sheet in May 1967
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 1967Explain the difference between irradiation and contamination.
- 2nd May 1967A 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.
- 3rd May 1967Explain why electricity is transmitted through the National Grid at a very high voltage rather than at the voltage used in homes.
- 4th May 1967A cube-shaped model cell has sides of length 3 cm. Calculate the surface area to volume ratio of the cube. Give your answer in the form n : 1.
- 5th May 1967Name the products of protein digestion.
- 6th May 1967State the difference between an antibiotic and a painkiller.
- 7th May 1967Name the chemical released at a synapse that carries the signal across the gap.
- 8th May 1967Explain why deforestation to create land for cattle grazing can reduce biodiversity.
- 9th May 1967Name the four stages usually considered in a life cycle assessment of a product.
- 10th May 1967A student says that metals conduct electricity because they contain free-moving ions. Explain why this statement is incorrect, and give the correct explanation.
- 11th May 1967Convert 250 cubic centimetres into cubic decimetres.
- 12th May 1967A 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.
- 13th May 1967State two products, other than water, that can be formed during the incomplete combustion of a hydrocarbon.

- 16th May 1967What happens to the total resistance when a second resistor is added in parallel, and why?
- 17th May 1967What happens inside the nucleus when a beta particle is emitted?
- 18th May 1967Explain why a larger vehicle mass increases braking distance.
- 19th May 1967State the type of force that always acts between an induced magnet and the magnet that induced it.

- 21st May 1967State three factors that increase the rate of diffusion.
- 22nd May 1967Which type of pathogen causes athlete's foot, a fungal skin infection?

- 27th May 1967Magnesium is burned in an open crucible and the mass increases. Explain why.
- 28th May 1967Explain why solid sodium chloride does not conduct electricity, but molten sodium chloride does.

- 30th May 1967Describe the result of the test for carbon dioxide.
- 31st May 1967Give one piece of evidence used to link human activity to recent climate change.
