Water of volume 2L in a closed container...

Water of volume 2L in a closed container is heated with a coil of 1 kW. While water is heated, the container loses energy at a rate of 160 J/s. In how much time will the temperature of water rise from `27^(@)C" to "77^(@)C`? (Specific heat of water is 4.2 kJ / kg and that of the container is negligible).

A
