Mean root square speed
WebExpert Answer. 15. The gas particles of an ideal gas a particular pressure and volume have a root-mean-square speed of vrms . If the pressure is of the gas is halved and the volume is held constant, what is the root-mean-square speed of the particles? (Hint: By what factor does the temperature change, and how is this related to the root-mean ... In the physics of gas molecules, the root-mean-square speed is defined as the square root of the average squared-speed.
