Max likes to drink tea. He uses his kettle to heat 1.6 liters of water from 18°C to 100°C every day. What does it cost him to heat the water per year (365 days) if he pays 29 cents per kWh of electricity. State the costs in euros to two decimal places. The material values of water averaged for the swept temperature range are: Cwater=4.18 kJ/(kg-K); pwater=983 kg/m3; Awater=0.654 W/(m2. K); nwater=467-10-6 kg/(m-s).
