MULTIPLE CHOICE QUESTION

30 sec • 1 pt

A sealed container of gas is compressed. Apply Boyle's Law to explain particle collisions and predict what happens if released?

pressure drops and volume expands quickly

pressure stays constant and volume expands

pressure rises further while volume shrinks

temperature decreases causing contraction

A balloon expands when heated. Use Charles' Law to explain why this happens and predict what occurs when cooled.

temperature decreases, so volume increases

temperature increases, so volume increases

pressure decreases while volume remains constant

volume decreases regardless of temperature

MULTIPLE CHOICE QUESTION

A football left outside on a cold day shrinks. Using Charles' Law, explain why this happens. Then, compare this situation to another real-world example of gases expanding or contracting with temperature (such as a hot-air balloon or a car tire). Justify how the law applies in both cases.

only the football shows Charles' Law; other examples are unrelated

both the football and other examples expand or contract with temperature changes due to Charles' Law

footballs shrink because of Boyle's Law, while balloons expand because of Dalton's Law

footballs and tires do not actually change in volume with temperature
