November 1999 - GCSE Science 5-a-day
Every GCSE Science sheet published in November 1999, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in November 1999
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 1999Two resistors are connected in parallel across a 12 V battery. State the potential difference across each resistor.
- 2nd November 1999A gas is heated in a sealed rigid container. Explain what happens to the pressure.
