3- Gas in a piston has a volume of 6.6 L, a temperature of 115 °C. If the final temperature is 173 °C, what will the final volume be?
a- 4.38 L
b- 9.9 L
C-5.47 L
d- 7.58 L

d- 7.58 L

Explanation:

According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.

Mathematically, V1/T1 = V2/ T2

V1= initial volume= 6.6 L

T1= Initial temperature= 115 °C= (115 °C +273)=388K

V2= final volume

T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K

Substitute the values,

V2=( V1 × T2)/ T1

= (6.6×446)/388

= 2943.6/388

= 7.6L
