Explanation:

Question 9

Charles's law states that for a fixed amount of gas at constant pressure, the volume is directly proportional to the absolute temperature. So, the amount of gas (b), pressure (d) are constant, and the type of piston (a) is irrelevant and also constant in the context of the law's variables. The volume (c) changes with temperature under Charles's law.

The relationship between the volume and pressure of a gas (when temperature and amount of gas are constant) is described by Boyle's Law, which states that \( P_1V_1 = P_2V_2 \) (pressure and volume are inversely proportional).

As a weather balloon rises, the atmospheric pressure decreases. According to Boyle's Law (for a fixed amount of gas at constant temperature, volume is inversely proportional to pressure), the gas inside the balloon will expand as pressure drops. If the balloon were fully inflated initially, the expanding gas would cause it to burst. So it's partially inflated to allow for expansion at higher altitudes with lower pressure.

Answer:

c. the volume of the gas.
