____ = ___

T1 T2


⚪︎ xy = k


⚪︎ V

__ = k

T


⚪︎ P1V1 = P2V2


⚪︎ PV = k

Answer:

V1/T1 = V2/T2

Explanation:

The Combined gas law for two states, 1 and 2, is given by:

P1V1/T1 = P2V2/T2

where P, V, and T are Pressure, Volume, and Temperature (always in degrees Kelvin).

If pressure is constant, the P1 and P2 cancel out:

V1/T1 = V2/T2

I can't tell from the formatting of the answers if A is this relationship.  Please compare.
