Question

Hey ♥️

Explain Charle's law !​

Answer 1

Hi friend here is your answer

_______________________________________

Charles law states that at constant pressure the volume of dry gas is directly proportional to absolute temperature

Charles law is expressed by

$V \alpha \: T$

Or

$\: \frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}$

V1 and V2 are the Initial Volume and Final Volume respectively. T1 refers to the Initial Temperature and T2 refers to the Final Temperature. Both the temperatures are in the units of Kelvin.

Derivation of Charles law

$V\alpha \: T$

$\frac{V}{T}=constant=k \:$

The value of k depends on the pressure of the gas, the amount of the gas and also on the unit of the volume.

Let V1 and T1 be the initial volume and temperature of an ideal gas.

$\frac{V_{1}}{T_{1}}=k \:$

By changing the temperature of the gas to T2. Its volume changes to V2.

$\frac{V_{2}}{T_{2}}=k \:$

Equating the above equations we get

$\frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}=k \:$

Answer 2

Answer:

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