particle motion in gases Flashcards
1
Q
what are the particles in gases like?
A
very far apart, and constant random motion
2
Q
how can we increase pressure of a gas?
A
increasing number of collisions per second or energy of each collision
3
Q
if we increase temp of a gas, what happens to its kinetic energy store?
A
kinetic energy increases
4
Q
what is the temperature of a gas related to?
A
average kinetic energy of its particles
5
Q
when temperature is low, pressure is low, why is this?
A
fewer collisions per second because of low kinetic energy
6
Q
when temperature is high, pressure is high, why is this?
A
more collisions per second because of high kinetic energy
