Every sheet in March 1966
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

- 9th March 1966State the four stages considered in a life cycle assessment.
- 10th March 1966Why does simple molecular carbon dioxide have a much lower melting point than giant covalent silicon dioxide?
- 11th March 1966Define oxidation in terms of electrons.
- 12th March 1966State two units that the rate of a reaction can be measured in.
- 13th March 1966State the functional group found in all carboxylic acids.
- 14th March 1966Explain why the natural greenhouse effect is necessary for life on Earth, rather than being a purely harmful process.
- 15th March 1966A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)

- 30th March 1966Explain why the baseline is drawn in pencil rather than ink.
- 31st March 1966Give one reason for taking the gradient from the line of best fit rather than from two data points.
