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 , the volume of water

When water is heated from 0^(@)C " to " 50^(@)C , density of water

An electric heater of resistance 10Omega connected to 220 V power supply is immersed in the water of 1 kg. How long the electrical heater has to be switched on to increase its temperature from 30^(@)C to 60^(@)C . (The specific heat of water is s=4200J kg^(-1) /C )

How much heat will be released when the temperature of 1 mol of water changes from 90^(@)C to 80^(@)C ? Given: specific heat of water 4.18J*g^(-1)*K^(-1) .

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

A 210 W heater is used to heat 100 g water. The time required to raise the temperature of this water from 25^(@)C to 100^(@)C is (specific heat capacity of water =4200" J/Kg-"^(@)C )

The specific heat capacity of water is ____ cal//g^(@)C

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).
