What happens to a real gas at high pressure that makes it become less ideal?
particles lose energy and so exert less pressure
particles gain energy and so exert more pressure
container volume decreases so particles occupy significant volume
container volume increases so particles occupy significant volume
What happens to a real gas at low temperatures that makes it behave less ideally?
particles have less energy and so exert less pressure on the container
particles have more energy and so exert more pressure on the container
volume of container decreases so particles occupy significant volume
volume of container increases so particles occupy significant volume
