Pressure in gases is caused by particles colliding close collisionWhen two or more things bump into each other. with the walls of the container. Gas pressure is increased when the temperature ...

Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.

So what is the ideal gas law? The super short answer is that it’s a relationship between the pressure, volume, temperature, and number of particles for a given gas. The equation looks like this: ...

A new study led by UW tested how Seattle's rush hour traffic impacted participants' blood pressure. Here's what the experiment found.
