increase
decrease
remain constant
decrease and increase in a constant cycle
At a constant volume for a sealed gas, as temperature decreases, pressure
decreases because the particles slow down and hit the inside of the container softer and less often.
decreases because the particles speed up and hit the inside of the container harder and more often.
increases because the particles slow down and hit the inside of the container softer and less often.
increases because the particles speed up and hit the inside of the container harder and more often.
What do the particles of a gas do when heated?
Move slower and come together
Move faster and come together
Move slower and spread apart
Move faster and spread apart
