Heat And Thermodynamics

An electrically heated coil is immersed in a calorimeter containing \(360 \mathrm{~g}\) of water at \(10^{\circ} \mathrm{C}\). The coil consumes energy at the rate of \(90 \mathrm{~W}\). The water equivalent of calorimeter and coil is \(40 \mathrm{~g}\). The temperature of water after \(10 \mathrm{~min}\) is
