An electric kettle takes 4 A current at 220 V . If the entire electric energy is converted into heat energy, then the time (in minutes) taken to increase the temperature of 1 kg of water from $34^{\circ} \mathrm{C}$ to $100^{\circ} \mathrm{C}$ is

According to Zeroth law of thermodynamics, the physical quantity which is same for two bodies in thermal equilibrium is

If a refrigerator of coefficient of performance of 5 has a freezer at a temperature of $-13^{\circ} \mathrm{C}$, then the room temperature is

From the figure shown for a thermodynamic system, match the curves with their respective thermodynamic processes.

( $p=$ Pressure and $V=$ volume )
