Question

a football that is inflated to maximum capacity while held inside a warm room will be slightly deflated when taken outside in cold temperatures. what relationship best explains this behavior?
○ gas molecules move more slowly at lower temperatures
○ volume and temperature are directly related; when one decreases, so does the other
○ pressure and volume are indirectly related; when one increases, the other decreases
○ volume and amount are directly related; when one decreases, so does the other

Explanation:

The football's air (a gas) has volume related to temperature. Charles's Law (ideal gas law concept) states volume and temperature (in Kelvin) are directly related for a fixed amount of gas at constant pressure. When temperature decreases (moving to cold outside), volume decreases (deflation). The option "volume and temperature are directly related; when one decreases, so does the other" matches this relationship. Other options: gas molecules moving slower is a fact but not the relationship explaining deflation; pressure - volume indirect relation (Boyle's Law) doesn't apply here (pressure isn't the main change factor here, temperature is); volume - amount direct relation (Avogadro's Law) doesn't apply as amount of gas in football is constant.

Answer:

The option: "volume and temperature are directly related; when one decreases, so does the other"
