An electric heating device consumes a current of 1.98 A when connected to the 220 V mains supply. If all the energy produced in 2.19 minutes is used to heat 2.08 kg of water, determine the rise in temperature of the device. (Specific heat capacity of water = 4200 J kg1 K-1) Note: - Express your answer in 2 decimal places. - No need to include the unit in the answer field. or ebould be in Oc
