Question

which quantity is held constant for boyle’s law, gay-lussac’s law, and charles’s law?
volume
mass
temperature
pressure

Explanation:

Boyle’s law relates pressure and volume (constant temperature and amount of gas, i.e., mass). Gay - Lussac’s law relates pressure and temperature (constant volume and amount of gas). Charles’s law relates volume and temperature (constant pressure and amount of gas). The amount of gas (related to mass, as mass of gas is proportional to the amount in moles) is held constant in all three gas laws. Volume, temperature, and pressure are the variables being related and change in each law, while the mass (amount) of the gas remains constant.

Answer:

B. mass
