Question:medium
A solid sphere has characteristic length $L_c = 0.02\text{ m}$, thermal conductivity $K = 40\text{ W/mK}$, and convective heat transfer coefficient $h = 10\text{ W/m}^2\text{K}$. Find the correct statement.

Show Hint
A low Biot number ($Bi < 0.1$) signifies high thermal conductivity and/or a small size, allowing heat to distribute rapidly throughout the solid, maintaining spatial temperature uniformity.

- 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:
