Question

V1T2 = V2T1 is an expression of who’s law

Answer 1

It is an expression of Charle's law.

Step-by-step explanation:

Charles' law:

It is one of the gas law.

It states that at constant pressure and for a given moles of a gas, the volume of the gas is directly proportional to the temperature (K).

If we increase the temperature of an ideal gas then at constant pressure and mole, the volume will increase linearly.

V α T

for two volumes at two different temperature

V₁ α T₁

And

V₂ α T₂

diving the two

V₁/V₂ = T₁/T₂

Or

V₁T₂=V₂T1

Answer 2

It is the expression of Charles' Law.

Step-by-step explanation:

The given expression V1T2 = V2T1 is the formula for the Charles' Law.

A special case of an ideal gas is named as the Charles' Law. This law applies to ideal gases only which are at constant pressure.

According to this law, the volume of a fixed mass of a gas is directly proportional to its temperature and is given by:

V1T2 = V2T1
