4.0 moles of krypton gas are in a 0.20 m3 container. The pressure is 1.663 × 105 Pa. a. What is the temperature (to the nearest K)? The volume contracts to 0.10 m3. The pressure is held constant. b. How much work was done by the gas during the volume contraction? c. What is the temperature after the volume contraction (to the nearest K)? d. What was the change in thermal energy? e. What was the heat flow? Express in units of J, positive = into gas, negative = out of gas.

Which of the following statements is not true according to kinetic theory?   a. The molecules in an ideal gas undergo elastic collisions.   b.

The average energy of a molecule in an ideal gas is evenly distributed between the different degrees of freedom of the molecule.   e. The energy of an ideal gas only depends on the kinetic energy of the gas.
