QUESTION 16
The temperature at state A is 20.0°C, that is 293 K. During the last test, you have found the temperature at state D is 73.0 K and n =
164 moles for this monatomic ideal gas. What is the change in thermal energy for process A to D, in MJ (MegaJoules)?
Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if
the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A cylinder contains 0.250 mol of carbon dioxide (CO₂) gas
at a temperature of 27.0°C. The cylinder is provided with a
frictionless piston, which maintains a constant pressure of
1.00 atm on the gas. The gas is heated until its temperature
increases to 127.0°C. Assume that the CO₂ may be treated
as an ideal gas.
