Question

a gas occupies a volume of 400cc on heating to 227degree c its volume becomes 1600 cc find the initial temperature of gas on celsius scale assuming that pressure remaining same

Answer 1

Pressure remains constant :-
We know
V1/T1 = V2/T2

Here V1 = 400cm³
V2 = 1600cm³
T1 = ?
T2=227°C
So just plug in the values we get :-
400/T1 = 1600/227°C
=> 1/T1 = 4/227
=> T1 = 227/4 = 56.75 °C

so initial temperature of the gas was 56.75°C
