Question

At constant pressure a gas at -23°C is heated to 127°C. Calculate the percentage increase in the volume of the gas

Answer 1

good ques ..

sol -- V1 = V , T1 = 247 K , T2 = 400 K

by charles law ,

V1/T1 = V2/T2 => V1*T2/T1 = V2

=> V2 = V*400/247

∆% = [(V*400/247 - V )*100/V ] %

= [ {(400V - 247V )/247 }*100/V ]%

= [(153V/247 )* 100/V ] %

= 61%
