Exercise 39

An automobile tire is filled to an absolute pressure of 3.0 atm at a temperature of 30°C. Later it is driven to a place where the temperature is only 20°C. What is the absolute pressure of the tire at the cold place (Assume that the air in the tire behaves as an ideal gas and the volume is constant.)
