An electrically heating coil was placed in a calorimeter containing `360g` of water at `10^(@)C`. The coil consumes energy at the rate of `70W`. The water equivalent of calorimeter and coil is `40g` . Find temperature of the water after `10min`. Given specific heat of water = `1 cal//g.^(@)C, 1 cal = 4.2J`.
