Question

A 113L sample of helium at 27°C is cooled at constant pressure to -78.0°C. Calculate the

Answer 1

Based on information the new volume of the helium is 73.45L.

New volume of the helium

Given:

Sample of helium at 27°C=113L

constant pressure=-78.0°C

Let v represent the new volume of the helium

Hence:

113/ 300= v/ 195

Cross multiply

300v=113×195

300v= 22035

Divide both side by 300v

v=22035/300

v=73.45L

Inconclusion the new volume of the helium is 73.45L.
