October 1956 5-a-day
Every sheet in October 1956
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st October 1956Name the three-domain system of classification, and name the scientist most associated with proposing it.
- 2nd October 1956Explain why large-scale deforestation increases the concentration of carbon dioxide in the atmosphere.
- 3rd October 1956State the four stages considered in a life cycle assessment.
- 4th October 1956Why does simple molecular carbon dioxide have a much lower melting point than giant covalent silicon dioxide?
- 5th October 1956Define oxidation in terms of electrons.
- 6th October 1956State two units that the rate of a reaction can be measured in.
- 7th October 1956State the functional group found in all alcohols.
- 8th October 1956Explain why the natural greenhouse effect is necessary for life on Earth, rather than being a purely harmful process.
- 9th October 1956A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)
