Question:medium
Match List-I with List-II (4-stroke petrol engine).
List-I List-II A. Inlet valve opens (IVO)
B. Inlet valve closes (IVC)
C. Exhaust valve opens (EVO)
D. Exhaust valve closes (EVC) I. 10°–15° after TDC
II. 30°–40° after BDC
III. 10°–20° before BDC
IV. 30°–50° before BDC
Match List-I with List-II (4-stroke petrol engine).
| List-I | List-II |
|---|---|
| A. Inlet valve opens (IVO) B. Inlet valve closes (IVC) C. Exhaust valve opens (EVO) D. Exhaust valve closes (EVC) | I. 10°–15° after TDC II. 30°–40° after BDC III. 10°–20° before BDC IV. 30°–50° before BDC |
Show Hint
Valve timing always overlaps near TDC for better efficiency.

Top Questions on Thermodynamics
- The difference of temperature in a material can convert heat energy into electrical energy. To harvest the heat energy, the material should have:
- JEE Main - 2025
- Physics
- Thermodynamics
- Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R): In an isothermal process, \( PV = \text{constant} \), while in an adiabatic process \( PV^\gamma = \text{constant} \). Here, \( \gamma \) is the ratio of specific heats, \( P \) is the pressure and \( V \) is the volume of the ideal gas.
In the light of the above statements, choose the correct answer from the options given below:- JEE Main - 2025

- Thermodynamics
- A poly-atomic molecule (C\(_3\)R, \(C_v = 4R\), where \(R\) is gas constant) goes from phase space point A (\(P_A = 10^4 \, \text{Pa}, V_A = 4 \times 10^{-3} \, \text{m}^3\)) to point B (\(P_B = 5 \times 10^4 \, \text{Pa}, V_B = 6 \times 10^{-7} \, \text{m}^3\)) to point C (\(P_C = 10^4 \, \text{Pa}, V_C = 8 \times 10^{-3} \, \text{m}^3\)). A to B is an adiabatic path and B to C is an isothermal path. The net heat absorbed per unit mole by the system is:
