Find the energy required to boil 0.250 kg of water away at 100ºC. The Latent Heat of Vapourisation of water is 2260 KJ/kg.
Lv of water = 2260 kJ per kg
565 000 J
565 J

In gases, pressure is
directly proportional to volume
inversely proportional to volume
directly proportional to friction
inversely proportional to heat
Gas pressure is caused by
Gas molecules heating up
Gas molecules reacting with other gas molecules
Gas molecules colliding with the walls of a container
Gas molecules colliding with other gas molecules
The temperature of gas is held constant, while its volume is decreased. The pressure exerted by the gas on the wall of the container increases, because its molecules
Strike the walls with higher velocities
Strike the walls with large farce
Strike the walls more frequently
Are in contact with the walls for a shorter time
