Question

A gas has a temperature of 14 oC and volume of 4.5 liters. If the temperature is raised to 29

Answer 1

Answer:

The new volume of the gas is 4.74L

Explanation:

Data;

T1 = 14°C = (14 + 273.15)K = 287.15K

V1 = 4.5L

T2 = 29°C = (29 + 273.15)K = 302.15

V2 = ?

From Charles law,

The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.

Mathematically,

V = kT

k = V1 / T1 = V2 / T2 = V3 / T3 = .............= Vn / Tn.

V1 / T1 = V2 / T2

Solving for V2

V2 = (V1 * T2) / T1

V2 = (4.5 * 302.15) / 287.15

V2 = 4.735L

V2 = 4.74L

The new volume of the gas is 4.74L
