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

Answer

Brief Explanations:

Boyle's law (pressure - volume, constant temperature), Gay - Lussac's law (pressure - temperature, constant volume), and Charles's law (volume - temperature, constant pressure) all deal with ideal gas behavior. The amount of gas (mass, since mass is related to the amount of substance for a given gas) remains constant in these gas laws as they describe the relationship between two variables while the amount of gas (and thus mass) is held fixed. Volume is not constant across all three (varies in Boyle's and Charles's), temperature not constant across all (varies in Boyle's and Gay - Lussac's), pressure not constant across all (varies in Charles's and Gay - Lussac's).

Answer:

B. mass
