`2` litres water at `27^(@)C` is heated by a `1kW` heater in an open container. On an average heat is lost to surroundings at the rate `160 J//s`. The time required for the temperature to reach `77^(@)C` is

A kettle with 2 litre water at 27^@C is heated by operating coil heater of power 1 kW. The heat is lost to the atmosphere at constant rate 160 J//s , when its lid is open. In how much time will water heated to 77^@C with the lid open ? (specific heat of water = 4.2 kJ//^@C-kg)
