To determine which constants should be filled in the first row of the table, let's analyze the given equation in that row: [tex]\( P_1 V_1 = P_2 V_2 \)[/tex].
This equation represents Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when the temperature and the number of moles of gas are held constant.
Thus, the constants for Boyle's Law are:
- Temperature
- Moles of gas
So, the constants that should be filled in the first row of the table are:
temperature and moles of gas
