Question

How well can you apply Charles’s law to this sample of gas that experiences changes in pressure and volume? Assume that pressure and number of moles of gas are constant in this problem. Using the first volume and temperature reading on the table as V1 and T1, solve for the unknown values in the table below. Remember to use the rules of significant figures when entering your numeric response. A: B: C: D:

Answer 1

Answer:

A: 383.5K

B: 0.847L

C: 1.1L

D: 221.6K

Explanation:

Hello,

From the attached picture one notices the possible options. In such a way, by considering the Charles' law:

$\frac{T_1}{V_1}= \frac{T_2}{V_2}$

- A: Here we find the temperature:

$T_2=\frac{T_1V_2}{V_1}=\frac{295K*1.3L}{1.0L} =383.5K$

- B: Here we find the volume:

$V_2=\frac{T_2V_1}{T_1}=\frac{250K*1.3L}{383.5K} =0.847L$

C: Here we find the volume:

$V_2=\frac{T_2V_1}{T_1}=\frac{325K*0.847L}{250K} =1.1L$

D: Here we find the temperature:

$T_2=\frac{T_1V_2}{V_1}=\frac{325K*0.75L}{1.1L} =221.6K$

Best regards.
