gas pressure Flashcards
1
Q
what is the pressure of gas caused by?
A
The pressure of a gas is caused by random particles hitting the container or surfaces
2
Q
what happens as you increase the temperature of a contained gas?
A
Increasing the temperature of a contained gas increases pressure as the particles move faster
3
Q
what is the Brownian motion?
A
Brownian motion is the random movement of particles can be seen in smoke.
4
Q
at a constant temperature, what happens when the pressure increases?
A
Pressure increases if volume decreases at a constant temperature
5
Q
how do you work out the mass of a gas held at a constant temperature?
A
For a fixed mass of gas held at a constant temperature: pressure x volume = constant ρv=constant
