Asample of an ideal gas is slowly compressed to one-half its original volume with no change in pressure. if the original root-mean-square speed (thermal speed) of the gas molecules was v, the new speed is squareroot 2v v1 squareroot 2 2 v v/2 v.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
