1- A car engine's cooling system con- tains 20.0 L of water (1 L of water has a mass of 1 kg).
a. What is the change in the temperature of the
water if 836.0 kJ of thermal energy is added?
b. Suppose that it is winter, and the car's cooling
system is filled with methanol. The density of
methanol is 0.80 g/cm². What would be the
increase in temperature of the methanol if it
absorbed 836.0 kJ of thermal energy?
c. Which coolant, water or methanol, would better
remove thermal energy from a car's engine?
Explain.
