An electric heater supplies (R+ 2.5) kW of power in the form of heat to water. If in 5.5 hours, 350 kg of water is heated from -10°C to 60 °C, find the work done (w) of heater. Also calculate the amount of heat energy (Q) transferred to the water. Consider the specific heat of water is 4184 J/kg K. R=30
