The cooling system of a car engine contains 20.0 Litre of water (1 L of water has a mass of 1 kg).

1. Which is the better coolant, water or methanol? Describe.

2. Assume it is winter and the system is filled with methanol. The density of methanol is 0.80 g/cm 3. What would be the increase in temperature of the methanol if it absorbed 836.0 kJ of heat?

3. What is the change in the temperature of the water if the engine operates until 836.0 kJ of heat are added?
