1. A helium-filled birthday balloon has a volume of 223 mL at a temperature of 24°C (room temperature). The balloon is placed in a car overnight during the winter where the temperature drops to -13°C. What is the balloon’s volume, in milliliters, when it is removed from the car in the morning (assuming no helium has escaped)?
