Question

Which equation is used to help form the combined gas law?

Answer 1

The ideal gas equation

Step-by-step 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:

`(PV)/(T)` = R

Therefore:

`(P_(1) V_(1) )/(T_(1) )` =
`(P_(2) V_(2) )/(T_(2) )`
