Describe what happens to gas pressure as temperature increases at constant volume.
A
Particles gain KE, move faster, collide more often/harder with walls — pressure increases
B
Pressure decreases as particles spread out at higher temperature
C
Pressure stays constant if volume is unchanged
D
Temperature and pressure are unrelated
