\(310\;J\) of heat is required to raise the temperature of 2 moles of an ideal gas at constant pressure from \(25^\circ C\) to \(35^\circ C\). The amount of heat required to raise the temperature of the gas through the same range at constant volume is
371509
Which of the two will require more work to be done? (i) compressing a gas isothermally until its volume is reduced by half (ii) compressing the same gas adiabatically until its volume is reduced by half
1 (ii)
2 It will depend upon the nature of the gas
3 (i)
4 Both will require the same amount of work
Explanation:
The area under \(P-V\) curve for isothermal curve is less than for adiabatic curve.

If \(Q,\,\,E\) and \(W\) denote respectively the heat added, change in internal energy and the work done in a closed cyclic process, then
1 \(Q = 0\)
2 \(W = 0\)
3 \(E = 0\)
4 \(Q = W = 0\)
Explanation:
In a cyclic process, a system starts from one point and ends at the same point. In that case, the change in the internal energy must be zero and therefore, the thermal energy added to the system must be equal to the work done during the cycle, i.e., in a cyclic process, \(\Rightarrow \quad E=0\)

Thermodynamic system returns to its original state, which of the following is NOT possible?
1 The work done is zero
2 The work done is positive
3 The work done is negative
4 The work done is independent of the path followed
Explanation:
Work is a path function so it depends on path.
PHXI12:THERMODYNAMICS

In a cyclic process, work done by the system is
1 Equal to the heat change across the system
2 Zero
3 Independent of heat given to the system
4 More than the heat given to system
Explanation:
For cyclic forces \(\Delta U=0\) So, \(\Delta Q=\Delta W\)
