pressure and moles of gas

Answer 1

The constants for the first row of the gas laws table, given the equation PV = k, are temperature and moles of gas, as per Boyle's law, which relates pressure and volume at constant temperature and amount of gas.

Step-by-step explanation:

The constants that would most likely be filled in the first row of the table, where the equation is PV = k, would be temperature and moles of gas. This equation represents Boyle's law, which states that for a given mass of an ideal gas at constant temperature, the volume is inversely proportional to the pressure. In other words, if the temperature and the amount of gas (in moles) are kept constant, the product of the pressure and volume will always be constant (k).

It is important to note that in gas laws, temperatures must always be expressed in kelvins because these laws are derived based on absolute temperatures. Boyle's law is one of several gas laws that describe the behavior of ideal gases under various conditions of pressure, volume, and temperature.

Answer 2

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.
