Question

It is required to reduce the volume
e the volume of a gas by 20% by compressing it at a constant pressure. To do so, the
gas has to be cooled. If the gas attains a final temperature of 157°C, find the initial temperature of the gas? please solve this​

Answer 1

Explanation:

let the initial volume is V1=100V

If the volume is reduced by 20% therefore it becomes... V2=100V--20V =80V

here given

initial temperature is T1=T

final temperature is =T2=157+273=430K

therefore according to Charles law.,

$\frac{v1}{t1} = \frac{v2}{t2}$

NOW

$\frac{100}{t1} = \frac{80}{430}$

$therfore \: \: \\ \\ t1 = \frac{100 \times 430}{80} = \frac{43000}{80}$

$t1 = \frac{4300}{8} = 537.5 \: kelvin$

hence the final temperature is 537.5 K. or 300K
