The initial pressure of a volume V1 of a fixed mass of gas is p1. The gas expands at a constant temperature until it has volume V2 and pressure p2. Which statement about the pressure and volume of the gas is not correct?
- APressure is measured in N / m3.
- BPressure multiplied by volume is a constant.
- CPressure is directly proportional to 1/volume.
- DThe ratio of V1 to V2 is equal to the ratio of p2 to p1.
