Question

at constant pressure a gas at -27°C is heated to 127°C find the percentage increase in the volume of the gas​

Answer 1

Answer:

T1 =-33℃ = -33 + 273 = 240 °k

T2 = 127 ℃= 127 + 273 = 400°k

as per Charles law,

V1/T1 = V2/T2

T2/T1 = V2/V1

V2/V1 = 400/240 = 5/3 = 1.6667

V2 =1.667*V1 = (166.67/100)*V1

so the % increase in Volume is

V2 - V1 = (1.667 - 1)*100 = 66.67%

hope it helps u a lot
