can someone help with this equation? thank you!

Question

A gas has a volume of 3.56 LL at ∘C. What final temperature, in degrees Celsius, is needed to change the volume of the gas to each of the following, if n and P do not change?

for 1270 mL?

Express your answer to three significant figures in degrees Celsius.

Answer 1

Hi,

From the above information, I see that the initial volume is 3.56L and the final volume is 1270mL. P,n, and R are constant and you are looking for the change in temperature.

Assuming that this question is at ideal gas state, we will use the equation PV=nRT.

Since the question stated that P, N, and R are constant, we can remove them from our equation which leaves us with V=T.

We are solving for the change in temperature as volume is changed. So, the equation is can be changed to

delta V = delta T --> delta meaning change.

(3.56L-1.270L)= delta T

delta T = 2.29 degree C.

The change in temperature is 2.29 degree C.
