A
Higher.
4
Q
If the volume of the container gets bigger, will the pressure be higher or lower?
A
The pressure will be lower.
5
Q
As you go up a mountain, will the pressure be higher or lower and why?
A
Lower because there are fewer gas particles.
6
Q
Why might a mountain climber take a oxygen tank with him?
