Question

The pressure of oxygen gas at 25 °C is 500 kPa. If the
volume of the gas is double, what will be its new pressure?

Answer 1

Answer:

Gas presure is the force that a gas exerts on

the walls of its container. It's calculated with

the pressure equation:

$pressure = \frac{force}{area}$

Although gas molecules can't be seen, they

exert pressure on the walls of their container

with their intermolecular collisions.
