The combined gas law sets up a relationship between which of the following?

A. pressure and temperature only

B. volume and temperature only

C. volume and pressure only

D. pressure, volume, and temperature

The correct option is D

Explanation:

The combined gas law is a combination of the three gas laws; Boyle's law, Charles' law and Gay-Lussac's law. It describes the relationship of the product of the pressure, volume and temperature of a gas to a constant as shown in the formula below

P₁V₁/T₁ = P₂V₂/T₂

Where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature (in Kelvin)

P₂ is the final pressure

V₂ is the final volume

T₂ is the final temperature (in Kelvin)

The combined gas law combines the three gas laws: Boyle's Law, Charles'Law, and Gay-Lussac's Law. It states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant. When Avogadro's law is added to the combined gas law, the ideal gas law res

Answer is volume and pressure only
