Water at 27°C is heated in an electric geyser of capacity 2 kW. If the geyser is filled with 20 L of water and heated for a duration of 20 minutes, find the temperature of water neglecting all the heat losses, assuming pressure inside the geyser as constant. (Take specific heat of the water as 5 kJ/kg)
