Which equation is used to help form the combined gas law?
kkurt [141]

Answer:

The ideal gas equation

Explanation:

The ideal gas equation is derived from the combination of three gas laws:

  • Boyle's law
  • Charles's law
  • Avogadro's law.

The ideal gas law is expressed mathematically as: PV=nRT where:

P is pressure

V is volume

n is the number of moles

R is the ideal gas law

T is temperature.

To obtain the combined gas law, we assume that n=1 and this gives:

                       \frac{PV}{T} = R

Therefore:

\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} }
