In this problem, V1 is unknown. T1 =127 C. V2 = 20.0 L. and T2=Negative 173 degrees C. Find V1. V1/T1=V2/T2. dont forget to change Celsius to
Kelvin before calculating.
*

Initial volume, V1 = 80L

Explanation:

Given the following data:

V2 = 20L

T1 = 127°C to Kelvin = 127 + 273 = 400K

T2 = -173°C to Kelvin = -173 + 273 = 100K

To find the initial volume V1, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

Making V1 the subject of formula, we have;

Substituting into the equation, we have;

Initial volume, V1 = 80L
