Question

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

Answer 1

Answer:

157.2 °C

Explanation:

The gas should be reducing 20% of its volume by compression. Compression has to be done by cooling itself. The final temperature is 157°C

The initial temperature must be

157+20% = x

157+ 20÷100 = x

157.2 = x

The final temperature of the problem is 157.2 °C
