. A sample of an ideal gas is contained at initial volume 34 L, temperature 450 K, and pressure 7.7 × 104 Pa. It then is allowed to expand to a volume of 40 L. To calculate the work involved in the expansion, which additional information, if any, must be known about the gas? Assume that known information includes the values of physical constants, such as the ideal-gas constant R.
A. the final pressure of the gas
B. The path of the change from initial to final conditions
C. the final temperature of the gas
