A gas undergoes a thermodynamic cycle consisting of three processes: (1) Isobaric expansion from $V_1$ to $2V_1$, (2) Isochoric cooling, and (3) Adiabatic compression back to the initial state. If the initial pressure and temperature are $P_1$ and $T_1$ respectively, and the temperature after the isobaric process is $T_2$, what is the net work done by the gas during one complete cycle?

Two different metallic rods of the same length have their ends kept at the same temperatures $heta_1$ and $heta_2$ with $heta_2 > heta_1$. If $A_1$ and $A_2$ are their cross-sectional areas, $K_1$ and $K_2$ their thermal conductivities, the rate of heat flow is the same in both the rods. The condition for this is:

A body cools from 50°C to 40°C in 5 minutes. The surrounding temperature is 20°C. In the next 5 minutes, it will cool approximately to:
