Boyle's Law represents the relationship of volume as pressure is changed. The constants of Boyle's Law are volume and temperature
pressure and volume
pressure and temperature
temperature and number of molecules of gas
pressure and number of molecules of gas
Answer temperature and number of molecules of gas.
Please ignore this question i just wanted to put the right answer out there cause the other question had it wrong and i couldnt type there

temperature and number of molecules of gas

Explanation:

Boyle's law is one of the gas laws, which states that the volume of a gas is inversely proportional to the pressure at a constant temperature. The Boyle's law equation is given as follows:

P ∝ (1/V)

P = K/V

PV = K

Based on these, the temperature of an ideal gas and the number of molecules in the gas are kept constant in Boyle's law.
