P1.3.1 - Gas pressure and temperature Flashcards
1
Q
What is pressure?
A
Pressure is the amount of force per unit area
2
Q
Why it is dangerous to throw a canister full of pressurised gas in a fire?
A
Heat from the fire will increase the temperature of the gas. The increase in temperature causes the pressure to rise. Once the pressure gets high enough it will cause the canister to explode
3
Q
What happens if you add more air particles to a container than cannot expand?
A
The pressure increases
4
Q
What happens if the temperature of a gas increases?
A
The particles will move faster which means they will collide more frequently with the sides of the container. This increases the pressure
5
Q
What is the pressure of gas measured in?
A
Pascals
6
Q
How can you measure the pressure of air trapped in a bottle?
A
You use a pressure gauge
