which constants would most likely be filled in the first row of the table?
temperature and moles of gas
volume and temperature
pressure and volume
pressure and moles of gas

I can't seem to tell which one is the first row since there is no table. So, I'll just fill in all the question marks for you.

Name: Boyle's Law
Variables: pressure and volume
Constants = gas constant and temperature
PV = k

Charles’s law
Volume and temperature
Gas constant and pressure
V = kT

Gay-Lussac's Law
Temperature, pressure
Gas constant and volume
P = kT

Combined gas law
Pressure, temperature, volume
Gas constant and moles of gas
PV=kT

The answers are those in bold letters for each section. Just see all of the sections so that you can see which one corresponds to the first row.
