If \(C_v\) is the specific heat capacity at constant volume of a gas, then the amount of heat required to increase the temperature of 2 moles of the gas from \(27^\circ\text{C}\) to \(127^\circ\text{C}\) at constant volume is

Heat supplied to a block of ice at \(0^{\circ}C\) converts it into steam at \(100^{\circ}C\). The curve that represents this change of state is.

Two bodies of same mass having temperature $T_1$ and $T_2$ place kept contact. Specific heat capacity of bodies are s and 1.2s respectively. find equilibrium temperature.

The amount of heat to be withdrawn from 3 kg of water at \(0^{\circ}C\) to obtain 3 kg of ice at \(0^{\circ}C\) in an icemaker is (latent heat of fusion of ice is \(80 \text{ kcal/kg}\))

Heat is conducted through a uniform rod ABC of length 1 m keeping the end A at \(100^{\circ}C\). If the temperature at the point B at a distance 0.4 m from the end A is \(80^{\circ}C\) and that at the other end C is \(40^{\circ}C\), then the ratio of heat conducted through AB to that through BC is

Two taps supply water to a container, one at the temperature of \(20^\circ\)C at the rate of \(2\) kg/minute and another at \(80^\circ\)C at the rate of \(1\) kg/minute. If the container gets water from the taps simultaneously for \(10\) minutes, then the temperature of water in the container is

Initially a beaker had $100$ g of water at temperature $90^\circ$C. Later another $600$ g of water at temperature $20^\circ$C was poured into the beaker. The temperature, $T$, of the water after mixing is

Hot water in a vessel kept in a room, cools from \(70^\circ C\) to \(65^\circ C\) in \(t_1\) minutes, from \(65^\circ C\) to \(60^\circ C\) in \(t_2\) minutes and from \(60^\circ C\) to \(55^\circ C\) in \(t_3\) minutes. Then
