If you double the average speed of the molecules in a gas, by what factor does the pressure change?10/30/2023 ![]() ![]() ![]() Gas molecules are in rapid and continuous motion at ordinary temperatures and pressures their velocities are of the order of 0.1-1 km/sec and each molecule experiences approximately 10 10collisions with other molecules every second. According to this model, most of the volume occupied by a gas is empty space this is the main feature that distinguishes gases from condensed states of matter (liquids and solids) in which neighboring molecules are constantly in contact. This fundamental assumption of the kinetic-molecular model helps us understand a wide range of commonly-observed phenomena. The molecules of a gas are in a state of perpetual motion in which the velocity (that is, the speed and direction) of each molecule is completely random and independent of that of the other molecules. The Fundamentals of Kinetic Molecular Theory (KMT)
