6.3.3.2 Pressure in Gases Flashcards
1
Q
How can a gas be compressed or expanded?
A
- pressure changes
2
Q
What does pressure produce?
A
- a net force at right angles to the wall of the gas container or any surface
3
Q
What can increasing the volume in which a gas is contained at a constant temperature lead to?
A
- decrease in pressure
- known of Boyle’s law
- this is due to the reduced number of collisions per unit area
4
Q
What is the equation for a fixed mass of gas held at a constant temperature?
A
- constant = pressure x volume
5
Q
What is pressure measured in?
A
- pascals
- Pa
6
Q
What is volume measured in?
A
- metres cubed
- m3
