Question

2.1 mol of an ideal gas isothermally expands from an initial pressure of 28 atm to a final pressure of 7 atm. Calculate separately for two temperatures, 0°C and 25°C, each of the following. (Include the sign of the value in your answer.)

(a) the work done on the gas (in kJ)

for T = 0°C and

for T = 25°C

(b) the change of internal energy of the gas (in kJ)

for T = 0°C and

for T = 25°C

(c) the amount of heat taken from the environment (in kJ)

for T = 0°C and

for T = 25°C
