The gas particles are constantly in motion, so they bounce off the walls of the container. The more particles within a container, the higher the pressure. Pressure is affected by change in temperature. The higher the temperature, the faster the particles move, the higher the pressure and vice versa.]]> 2021-02-23 16:23:39 UTC https://padlet.com/geraldinemathews/gpp4gc7v5z6odg12/wish/1232280041 adeleanu3585 https://padlet.com/geraldinemathews/gpp4gc7v5z6odg12/wish/1232282752 Merriam-Webster defines pressure as

This is because of gravity pulling air towards the earth’s surface, and density because as altitude increases, the number of gas molecules decreases, making the air less dense. Climate can impact the air pressure of an altitude. Even if two places have the same altitude, their air pressures can vary due to the humidity.
