Question

which quantity is held constant for boyles law, gay-lussacs law, and charless law?
○ volume
○ mass
○ temperature
○ pressure

Explanation:

Boyle’s law (pressure - volume, constant temperature), Gay - Lussac’s law (pressure - temperature, constant volume), and Charles’s law (volume - temperature, constant pressure) all involve a fixed amount of gas. The amount of gas is related to mass (since mass of gas particles remains the same in these ideal gas law applications). Volume, temperature, and pressure vary in each law, but mass (amount of gas) is constant.

Answer:

B. mass
