JEE AdvancedPhysicsHeat and ThermodynamicsMultiple correct+4 / −1
One mole of a monatomic ideal gas goes through a thermodynamic cycle, as shown in the volume versus temperature (V-T) diagram. The correct statement(s) is/are [R is the gas constant] JEE Advanced 2019 Paper 1 Offline Physics - Heat and Thermodynamics Question 47 English
  1. A
    Work done in this thermodynamic cycle (1 →\to→ 2 →\to→ 3 →\to→ 4 →\to→ 1) is ∣W∣=12RT0\left| W \right| = {1 \over 2}R{T_0}∣W∣=21​RT0​.
  2. B
    The ratio of heat transfer during processes 1 →\to→ 2 and 2 →\to→ 3 is ∣Q1→2Q2→3∣=53\left| {{{{Q_{1 \to 2}}} \over {{Q_{2 \to 3}}}}} \right| = {5 \over 3}​Q2→3​Q1→2​​​=35​
  3. C
    The above thermodynamic cycle exhibits only isochoric and adiabatic processes.
  4. D
    The ratio of heat transfer during processes 1 →\to→ 2 and 3 →\to→ 4 is ∣Q1→2Q3→4∣=12\left| {{{{Q_{1 \to 2}}} \over {{Q_{3 \to 4}}}}} \right| = {1 \over 2}​Q3→4​Q1→2​​​=21​
