1) a.The air pressure inside the tube of a car tire is 341.0 kPa at a temperature of 14.5 °C. What is the pressure of the air, if the temperature of the tire increases to 56.5 °C? Assume that the volume of the tube doesn't change. b.What is the air pressure inside the tube, if the volume of the tube is not constant, but it increases from 21.2 l to 21.7 l during the warming process described above?
2)The pressure inside a gas bottle is 3180 kPa when the temperature is 26.1 °C. What will be the pressure inside the bottle, if 42.8 percent of the gas is released and the temperature of the gas drops to 4.3 °C?
