Chapter 5 - Gases and the Kinetic Energy Theory

atmosphere

Our _________ is a colorless, odorless mixture of 18 gases, several of which- O2, N2, H2O vapor, and CO2- play important roles in the environment's life-sustaining redox processes.

pressure= force /area

The force exerted per unit of the charge a bond surface area is denoted as pressure (P): _______ The gases in the atmosphere exert a consistent force (or weight) on all surfaces, resulting in atmospheric pressure, which is generally around 14.7 pounds per square inch (lb /in2); psi) of surface pressure.

gas cools

When a ________, its density rises because its volume decreases, when the temperature drops from 20°C to 0°C, the density of O2 (g) rises from 1.3 to 1.4 g /L.

Gas

takes on the shape of a container and fills it

Liquid

takes on the form of a container to the degree of its volume
