C1.7 - Gas Pressure Flashcards
What happens to gas pressure if you decrease the temperature?
It decreases.
Why does gas pressure increase if you add more air particles to a sealed container?
Because there are more air parrticles colliding with the inside of the container.
What does the word ‘collide’ mean?
Crash into something
What happens to gas pressure if you increase the temperature?
It increases
Describe how air particles are behaving when they are inside a balloon?
They are flying around randomly.
They collide into each other.
They are colliding off the inside walls of the balloon.
When air particles collide off the inside walls of a balloon they exert a force. What do we call this force?
Gas Pressure
If you increase the number of air particles inside a fixed container, what happens to the gas pressure inside the container?
It increases
