A water heater can generate 8500 kcal/hr. How much water can it heat from `10^(@)C` to `60^(@)C` per hour? Use specific heat of water `4500Jkg.^(@)C`

When water is heated from 0^(@)C to 10^(@)C , its volume

When water is heated from 0^(@)C to 10^(@)C , the volume of water

An immersion heater is rated 836 watt . It should heat 1 litre of water from 10^(@)C to 40^(@)C in about

Water of volume 4L in a closed container is heated with a coil of 2 kW. While water is heated, the container loses energy at a rate of 120 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 swimming pool contains 1 xx 10^(5) L of water.How much energy in joules is required to raise the temperature of water from 20^(@)C to 25^(@)C ? The specific heat capacity of water is (4.184 J)/(.^(@)C) g.
