Gas pressure Flashcards
1
Q
What is the pressure in a gas caused by?
A
Random particles hitting the container or surfaces
2
Q
What does increasing the temperature of a contained gas do?
A
Increases pressure as the particles move faster
3
Q
What is Brownian motion?
A
The random movement of particles - can be seen in smoke
4
Q
When does pressure increase?
A
Pressure increases if volume decreases at a constant temperature
5
Q
What is the equation for a fixed mass of gas held at a constant temperature?
A
pressure x volume = constant ρv = constant
