Question

Explain Charles Law and its graphical representation also.

Answer 1

Charles' Law states that the volume (V) of a confined gas is directly proportional to its temperature (T) in Kelvin.
When the temperature changes one unit on the Kelvin scale it is equivalent to a change in one Celsius degree; that is, they are in a one-to-one correspondence. Note that 0 on the Kevin scalerepresents "Absolute Zero" or -273 º.


Graph between V and T at constant pressure is called isobar or isoplestics and is always a straight line. A plot of V versus t(°C) at constant pressure is a straight line cutting the temperature axis at – 273.15°C. It is the lowest possible temperature.

At constant mass and pressure density of a gas is inversely proportional to it absolute temperature. 

   

Answer 2

$\huge\textbf{Charles Law}$

At constant Pressure (P), Volume (V) of a given mass of gas is directly proportional to the Temperature (T) of gas.

$V$ $\alpha$ $T$

(At constant Pressure)

$V\:=\:k\:×\:T$

$\frac{V}{T}$ $=\:k$

$\frac{V1}{T1}$ $=\:k$

$\frac{V2}{T2}$ $=\:k$

Here k = Constant

So,

$\frac{V1}{T1}$ = $\frac{V2}{T2}$
