Question

A sample of a gas in a balloon has a volume of 4.20 L and temperature of 48.2 °C. Calculate the volume when
the temperature is lowered to 15.4°C at constant pressure.
a. 3.77
b. 4.20
c. 1.34
d. 13.15
e. 4.68

Answer 1

Answer:

V1/T1=V2/T2

4.20L/321.2K=x/288.4K

multiply both side by 288.4

1211.28/321.2=x

x=3.77L

Answer 2

Option 3 13.15 is the  correct answer.

What is Charles law?

Charles's law exists as an experimental gas law that explains how gases tend to expand when heated. A modern statement of Charles's law exists: When the pressure on a sample of a dry gas exists held constant, the Kelvin temperature and the volume will be in direct proportion.

According to Charles law

The volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.

$V1/T1=V2/T2$

Where,

$V1$= first volume

$V{2}$ = second volume

$T{1}$ = first temperature

$T{2}$= second temperature

Here, at constant pressure,

$V1/T1=V2/T2$

$V1$=4.20 L

$V2$= x

$T1$=321.2 K

$T2$=288.4 K

Therefore, $V1/T1=V2/T2$

4.20L/321.2K=x/288.4K

1211.28/321.2=x

x=3.77L

Thus option a is correct.
