Pressure in a Gas

Gas Pressure is created when gas particles collide with the walls of their container. The more often the particles collide with the walls, and the faster they are moving, the greater the pressure.

Demo

In this tutorial you will learn how to calculate the gas pressure in enclosed spaces depending on the containers volume.

The formula for this equation is written like this:

$pV = { \text K}$

Chilled practice question

A gas in a sealed container has a volume of 12 m3. The pressure of the gas is 80 Pa. The volume of the container is increased and the pressure falls to 60 Pa. What is the new volume of the container ? The temperature of the gas remains unchanged.

The volume of a gas is reduced from 10 m3 to 2.5 m3 . The original pressure is 200 Pa. Calculate the new pressure.

Science in context

Pressure in a gas is caused when gas particles collide with the walls of their container. The more often the particles collide with the walls, and the faster they are moving when they do this, the greater the pressure. This is why the pressure in a tyre goes up when more air is pumped in.

Forces and Work Done

The unit for work done is the joule (J), or Newton meter (N-m). One joule is equal to the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

Demo

In this tutorial you will learn how to calculate the work done to move an object through a known distance.

The formula for this equation is written like this:

w = f x d

75 J of work is done pulling a trolley 150 cm. Calculate the force applied.

Science in context

Work can be calculated with the equation: Work = Force × Distance. The unit for work is the joule (J), or Newton • meter (N • m). One joule is equal to the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
