A radiator has water in it filled to the top when the engine is cold. (a) What happens to the water when the engine is running, and the water temperature has risen? (b) What do modern car engines have in their cooling system to prevent the loss of coolant?
A certain car has 14 L of coolant circulating at a temperature of 95 degrees Celsius through the engine’s cooling system. Assume that, in this normal condition, the coolant completely fills the 3.5 L volume of the aluminum radiator and the 10.5 L internal cavities within the aluminum engine. When a car overheats, the radiator, engine, and coolant expand and a small reservoir connected to the radiator catches any resultant coolant overflow. Estimate how much coolant overflows to the reservoir if the system goes from 95 degrees Celsius to 106 degrees Celsius. Model the radiator and engine as hollow shells of aluminum. The coefficient of volume expansion for coolant is 410x10^-6 degrees Celsius
