1 Liter (1,000 cm³) of water is inside a 1.01 L ordinary glass water bottle and is thrown into the back seat of a car traveling to a lake. During the time the car with rolled up windows is parked in the Sun, the glass water bottle and the water inside goes from a temperature of 20°C to 55°C. The air trapped inside the water bottle was at 1 atm of absolute pressure when the bottle was capped sealed at 20°C. a) Convert 55°C to °F. b) Calculate the change in volume of the water and the glass bottle. c) Calculate the new volume of air inside the bottle.
