Every sheet in August 1996
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 1996Why is an atom electrically neutral?
- 2nd August 1996State the law of conservation of mass.
- 3rd August 1996State the name given to the negative electrode in electrolysis.
- 4th August 1996Explain why using a light sensor and data logger is more reliable than timing by eye in the disappearing cross practical.
- 5th August 1996Give one piece of evidence that a solid sample is impure, based on its melting behaviour.
- 6th August 1996Explain why carbon monoxide is dangerous even though it has no smell.
- 7th August 1996Why can no device be 100 percent efficient?
- 8th August 1996Why is melting described as a physical change?
- 9th August 1996A cyclist rides 300 m north then 300 m back south to the start. State the total distance travelled and total displacement.
- 10th August 1996Explain, in terms of particle motion, why a wave can transfer energy without transferring matter.
- 11th August 1996Name the region of the Solar System where most asteroids are found.
- 12th August 1996Convert 0.05 mm into micrometres.
- 13th August 1996State the function of the valves in the heart and in veins.
- 14th August 1996A lamp is placed 10 cm from pondweed. Calculate the relative light intensity using relative light intensity = 1 / distance^2.
- 15th August 1996A person's blood glucose concentration is 4.8 mmol/dm^3 before breakfast and 7.2 mmol/dm^3 after breakfast. Calculate the increase in blood glucose concentration.
- 16th August 1996The Arctic fox has small, rounded ears compared with the desert fennec fox, which has very large ears. State whether this is a structural, behavioural or functional adaptation, and explain how it helps the Arctic fox survive.
- 17th August 1996Classify crude oil as finite or renewable, and justify your answer.
- 18th August 1996Write the formula of calcium chloride and explain the ratio.
- 19th August 1996Calculate the number of moles of sodium hydroxide in 200 cm3 of a 0.500 mol/dm3 solution.
