Question 1 Report
A sample of gas with an initial volume of 2.5 dm3 is heated and then allowed to expand to 7.5 dm3 at constant at pressure. What is the ratio of the final temperature of the initial absolute temperature?
Answer Details
According to Charles's Law, the ratio of the initial and final temperatures is equal to the ratio of the initial and final volumes at constant pressure.
The ratio of the final volume to the initial volume is:
Vf / Vi = 7.5 dm3 / 2.5 dm3 = 3
Therefore, the ratio of the final temperature to the initial temperature is also 3:
Tf / Ti = Vf / Vi = 3
So the answer is 3:1.
