- If the temperature of a fixed mass of a gas is kept constant and the pressure is increased, the volume correspondingly ………….. [increases/decreases]
- If the pressure of a fixed mass of a gas is kept constant and the temperature is increased, the volume correspondingly ………….. [increases/decreases]
- 1 dm3 of a gas is equal to ………….. [1 litre / 100 ml. / 100 cc.]
- All the temperatures on the kelvin scale are in ………….. figures [negative/positive]
- At -273°C the volume of a gas is theoretically ………….. [272 cc. / 0 cc. /274 cc.]
Answer
- If the temperature of a fixed mass of a gas is kept constant and the pressure is increased, the volume correspondingly decreases.
- If the pressure of a fixed mass of a gas is kept constant and the temperature is increased, the volume correspondingly increases.
- 1 dm3 of a gas is equal to 1 litre.
- All the temperatures on the kelvin scale are in positive figures.
- At -273°C the volume of a gas is theoretically 0 cc.
