Pressure

100

Which statement regarding gas pressure is FALSE?

1. Gas Pressure increases as volume of container  increases

2. Gas Pressure increases with concentration

3. Gas Pressure increases with temperature

4. Gas Pressure increases as rate of collisions increases

(1) 

Gas Pressure increases as volume of container increases

200

Pressure is equal to...

Force/Area

300

Why does gas pressure increase when you increase the amount of molecules in a container?

It leads to an increase in the amount of collisions that occur between the molecules and an increase with the amount of molecules that collide against the container. 

400

TRUE OR FALSE

The relationship between pressure and volume is direct.

FALSE 

(As volume decreases, pressure increases)
