Define about the Heat Loss?

An immersion heater of power J=500 W can be used to heat water in a bowl. After 2 minutes the temperature enhance from T1=85oC to T2=90°C. The heater is after that switched off for an additional minute and the temperature drops ΔT = 1°C. By estimation the mass of the water in the bowl and The thermal capacity of water c= 4.2 • 103j/kg K.
