Question

State and explain Charles law. How does this leads to the concept of absolute zero ? How does this law made use in the metrological observation ?

Answer 1

Explanation:

Charles's law (also known as the law of volumes) 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 proportion.[1]

This relationship of direct proportion can be written as:

{\displaystyle V\propto T}{\displaystyle V\propto T}

So this means:

{\displaystyle {\frac {V}{T}}=k,\quad or\quad V=kT}{\displaystyle {\frac {V}{T}}=k,\quad or\quad V=kT}

where:

V is the volume of the gas,

T is the temperature of the gas (measured in kelvins),

and k is a non-zero constant.

This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions,

The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.
