At 100 °C, which of the following diagrams (1, 2, or 3) represents a gas sample that exerts the: (8.1)b. highest pressure??

Gas pressure is the force exerted by gas particles colliding with the walls of their container. It is influenced by the number of particles, their speed, and the volume of the container. Higher temperatures increase the kinetic energy of gas molecules, leading to more frequent and forceful collisions, which results in higher pressure.

The Kinetic Molecular Theory explains the behavior of gases in terms of particle motion. It posits that gas particles are in constant, random motion and that their kinetic energy is directly proportional to the temperature of the gas. This theory helps to understand how changes in temperature and volume affect gas pressure.

The Ideal Gas Law, represented as PV = nRT, relates pressure (P), volume (V), number of moles (n), the ideal gas constant (R), and temperature (T). This equation allows for the calculation of one variable when the others are known, providing a framework for understanding how gases behave under different conditions, including pressure at a given temperature.
