Answer 2

Answer:

• Thermal contraction is the opposite of thermal expansion. When the temperature drops, atoms calm down and shrink.
• Thermal expansion and contraction affect the volumes of liquids that
• are used every day. Cars provide a good example of this. Cold gasoline
• in a car’s gas tank expands in hot weather. If the tank is filled to the
• brim, the gas may overflow. Also, if a car engine is filled with cold
• liquid coolant, the coolant will warm up and expand when the car is
• running, and may overflow.
• Thermal expansion and contraction affect the volume and pressure
• of tires, volleyballs, and basketballs.
