Worked example
One question from this skill's own question bank, shown with its full working.
Boyle's law states that, at constant temperature, the pressure of a fixed mass of gas is...
- inversely proportional to its volume
- directly proportional to its volume
- equal to its volume
- independent of its volume
Working: Boyle's law: PV = constant, so pressure rises as volume falls.
