A
Pascal (Pa)
4
Q
what is one Pascal equivalent to?
A
1 N/m^2
5
Q
what do we use to describe gas pressure?
A
a particle model
6
Q
as temperature increases what happens to gas pressure and why?
A
as temperature increases gas pressure increase:
-particles go faster as they gain kinetic energy
-particles hit walls more often with more force

A
-273°C
8
Q
what does gas pressure depend on?
A
-temperature
-volume
