question 10

Multiple Choice

• A)The internal (thermal)energy of the gas in both flasks is the same.
• B)The internal (thermal)energy of the gas in the larger flask is greater than the internal (thermal)energy of the gas in the smaller flask.
• C)The internal (thermal)energy of the gas in the smaller flask is greater than the internal (thermal)energy of the gas in the larger flask.
• D)The molecules in the larger flask have the same root-mean-square speed as those in the smaller flask.
• E)The molecules in the smaller flask have the same average kinetic energy per molecule as those in the larger flask.
