The logarithmic mean temperature difference (LMTD) method is used to:
The logarithmic mean temperature difference (LMTD) method is used to:
Show Hint
If the temperature differences at both ends of the heat exchanger are equal ($\Delta T_1 = \Delta T_2$), then the logarithmic mean is exactly equal to the arithmetic mean.
For all other cases, the logarithmic mean is always strictly less than the arithmetic mean.
For all other cases, the logarithmic mean is always strictly less than the arithmetic mean.

- The difference of temperature in a material can convert heat energy into electrical energy. To harvest the heat energy, the material should have:

- 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

- 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:
