Question

state and explain charls law

Answer 1

Charle’s Law -- It states that, for an ideal gas at constant pressure, the volume is directly proportional to its temperature. The relation is given by:

(V1/T1 = V2/T2)

where,

V1 = Initial Volume,

T1 = Initial Temperature,

V2 = Final Volume.

T2= Final Temperature,

 

Charles' Law Example: A football inflated inside and then taken outdoors on a winter day shrinks slightly.

 

Charles' Law Example, problem: A certain amount of gas occupies a volume of 60 L at 300 K temperature. Find the temperature of the gas which has a volume of 100 L.

 V1 = 60 L, T1 = 300 K, V2 = 100 L

 Substitute the values in the below final temperature equation:

  Final Temperature(T2) = V2T1 / V1

   = (100 x 300) / 60

  = 30000 / 60

  Final Temperature(T2) = 500 K

This example will guide you to calculate the final temperature manually.

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,

$\frac{V1}{T1}$ = $\frac{V2}{T2}$
