Figure shows two processes A and B on a system. Let ΔQ1\Delta Q_1 and ΔQ2\Delta Q_2 be the heat given to the system in processes A and B respectively. Then ____________.

Multiple Choice Options

  • A ΔQ1>ΔQ2\Delta Q_1 > \Delta Q_2
  • B ΔQ1=ΔQ2\Delta Q_1 = \Delta Q_2
  • C ΔQ1<ΔQ2\Delta Q_1 < \Delta Q_2
  • D ΔQ1≤ΔQ2\Delta Q_1 \le \Delta Q_2

Step-by-Step Verified Solution

**Answer:** (a) _Q_ > _Q_. **Step-by-Step Explanation:** From the figure, process A has a larger area under the curve, so more work is done. Since _U is the same for both, _Q = _U + _W, so _Q_ > _Q_.
