(a)
Interpretation: The change in temperature for 1 mole of an ideal gas needs to be determined if heat released is 425 J and work done on the system is 185 J.
Concept Introduction: The change in internal energy is calculated as follows:
Here, n is number of moles,
The work done is represented as follows:
Here, P is external pressure and
The enthalpy of a reaction is represented as follows:
Here, n is number of moles, R is Universal gas constant and
