Mean relative speed physical chemistry

WebThe energy that the system loses is given out as heat. The surroundings warm up. For an endothermic change: This time the products have a higher energy than the reactants. The system absorbs this extra energy as heat from the surroundings. Expressing exothermic and endothermic changes in numbers WebThe root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas. It is represented by the equation: v_ {rms}=\sqrt {\frac {3RT} {M}} vrms = M 3RT
