At what temp will a gas be at if you allow it to expand from an original 456 ml to 65°c to 3.4 l

Answer : The initial temperature of gas will be, 45.33 K

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,

= initial volume of gas = 456 ml  = 0.456 L

conversion used : (1 L = 1000 ml)

= final volume of gas = 3.4 L

= initial temperature of gas = ?

= final temperature of gas =

Now put all the given values in the above formula, we get the initial temperature of the gas.

Therefore, the initial temperature of gas will be, 45.33 K
