An electric immersion heater of `1.08 kW` is immersed in water . After it has reaches a temperature of `100^(@)C` , how much time will be required to produce `100 g` of steam?

If steam of mass 100g and temperature 100^(@)C is released on an ice slab of temperature 0^(@)C , how much ice will melt ?

An immersion type electric heater of 250 watts is immersed in 5 kg of water contained in a bucket. In how much time will the temperature water rise by 10^(@)C ? Sp heat capacity of water 1000cal kg^(-1)K^(-1) and J=4.1J cal ^(-1) . Neglect heat capacity of bucket.

Consider 4 kg of water at 100^@C . How much amount of heat is required to convert it into steam ?

Give reason of boiling water and steam both have the same temperature (100^(@)C) , but steam causes much severe burns than boiling water.

A heating coil of 2000 W is immersed in water . How much time will it take in raising the temperature of 1 L of water from 4^(@) C "to" 100^(@) C ? Only 80% of the thermal energy produced is used in raising the temperature of water.

600 g of water at 30^(@)C is kept in a vessel of water equivalent 60 g. If the vessel is supplied heat at the rate of "100 cal.s"^(-1) , how much time will the water take to reach its boiling point?
