which quantity is held constant when working with boyles, charless, and gay - lussacs laws?\nvolume\nmoles\np…

Brief Explanations:

Boyle's law ($P_1V_1 = P_2V_2$), Charles's law ($\frac{V_1}{T_1}=\frac{V_2}{T_2}$), and Gay - Lussac's law ($\frac{P_1}{T_1}=\frac{P_2}{T_2}$) are all based on the assumption that the amount of gas (number of moles) remains constant. These laws deal with relationships between pressure, volume, and temperature of a gas sample, but the number of moles is held fixed.

Answer:

moles
