    Question

    Gas at a pressure P0 is contained in a vessel. If the masses of all the molecules are halved and their speeds are doubled, the resulting pressure P will be equal to

    1. 4P0
    2. 2P0
    3. P0
    4. p subscript 0 over 2

    The correct answer is: 2P0

      P equals 1 third rho open parentheses straight v subscript r m s end subscript close parentheses squared not stretchy rightwards double arrow P proportional to m open parentheses straight v subscript r m s end subscript close parentheses squared
