Question

what was changed when the temperature was changed in the \gas laws\ lab?
mass and volume
weight and volume
gravity and volume
volume and pressure

Explanation:

Gas laws (like Charles's Law, Gay-Lussac's Law, and the Ideal Gas Law) describe that for a fixed amount of gas, changing temperature affects volume (at constant pressure) and pressure (at constant volume). Mass, weight, and gravity are not altered by temperature changes in this context, as the amount of gas and gravitational force remain constant.

Answer:

volume and pressure
