August 2004 - GCSE Science 5-a-day
Every GCSE Science sheet published in August 2004, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in August 2004
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 2004State the four factors that can increase the rate of a chemical reaction.
- 2nd August 2004Name the small molecule typically released as a by-product during condensation polymerisation.
- 3rd August 2004Describe, in terms of wavelength, the difference between the radiation the Earth receives from the Sun and the radiation it re-emits from its surface.
