DifficultThree containers $C_{1}, C_{2}$ and $C_{3}$ have water at different temperatures. The table below shows the final temperature $T$ when different amounts of water (given in litres) are taken from each container and mixed (assume no loss of heat during the process).
$C_{1}$ $C_{2}$ $C_{3}$ $T$ $1 \ l$ $2 \ l$ $-$ $60^{\circ} C$ $-$ $1 \ l$ $2 \ l$ $30^{\circ} C$ $2 \ l$ $-$ $1 \ l$ $60^{\circ} C$ $1 \ l$ $1 \ l$ $1 \ l$ $\theta$
The value of $\theta$ (in $^{\circ} C$ to the nearest integer) is
| $C_{1}$ | $C_{2}$ | $C_{3}$ | $T$ |
| $1 \ l$ | $2 \ l$ | $-$ | $60^{\circ} C$ |
| $-$ | $1 \ l$ | $2 \ l$ | $30^{\circ} C$ |
| $2 \ l$ | $-$ | $1 \ l$ | $60^{\circ} C$ |
| $1 \ l$ | $1 \ l$ | $1 \ l$ | $\theta$ |
The value of $\theta$ (in $^{\circ} C$ to the nearest integer) is
- A$45$
- B$48$
- C$55$

Water of volume $2 \, L$ in a container is heated with a coil of $1 \, kW$ at $27 \, ^\circ C$. The lid of the container is open and energy dissipates at a rate of $160 \, J/s$. In how much time will the temperature rise from $27 \, ^\circ C$ to $77 \, ^\circ C$? [Given: specific heat of water is $4.2 \, kJ/(kg \cdot K)$]

View SolutionTwo identical bodies are made of a material for which the heat capacity increases with temperature. One of these is held at a temperature of $100^{\circ} C$,while the other one is kept at $0^{\circ} C$. If the two are brought into contact,then assuming no heat loss to the environment,the final temperature that they will reach is

View SolutionSteam at $100^{\circ} C$ is passed into $1 \ kg$ of water contained in a calorimeter of water equivalent $0.2 \ kg$ at $9^{\circ} C$ until the temperature of the calorimeter and water in it increases to $90^{\circ} C$. The mass of steam condensed in $kg$ is nearly (specific heat of water $= 1 \ cal/g^{\circ} C$,latent heat of vaporisation $= 540 \ cal/g$)
