Question

State Charle's Law. Give its Mathematical Expression

Answer 1

$\huge\textbf{Charles Law}$

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,

$\frac{V1}{T1}$ = $\frac{V2}{T2}$

Answer 2

$\textbf{\large{Answer -}}$

At constant temperature, the volume of a given mass of a gas increases or decreases by 1/273th of it's volume at o° C then every one centigrade rises or falls in temperature.

i.e.,

$V_{t}=V_{0}+\frac{V_{0}}{273}\times t$

Here,

$V_{t}$ = volume of gas at t° C

$V_{0}$ = vomume of gas at 0° C

$t$ = temperature
