A hollow container is filled with an ideal gas. The container is designed to maintain a constant pressure by allowing gas to enter or leave as needed. at all times the gas and container are in thermal equilibrium. initially the temperature is 1078 K. then the temperature decreases to 200 K and the volume decreases to .88 times the initial volume. determine the coefficient of volume expansion for the container and the ratio of the final number of moles to the initial number of moles. Please include the units, and round to the fourth decimal point.
