| Name:_______________________________ Student Number:______________________________ Quiz 1 Variables in bold were different for each student. 1. A sample of one mole of helium gas in a rigid-walled container at T1 degrees Celsius was measured to be p1 kPa. Calculate the pressure in kPa of this sample when the temperature is T2 degrees Celsius. Be sure that your final answer has the correct number of significant digits. You must show your work.

Unformatted text preview: 1 1 T p T p = (constant volume, remember to use SI units) Solve for p2. 2. Calculate the amount of work done by the gas if the 2L container is suddenly opened to the atmosphere (101325Pa) while maintaining the temperature at T2 Celsius. ∫ Δ − = − = V p pdV w ext (expansion against a constant external pressure) P ext = 101325 Pa V1 = 2L (if you calculated V1 is problem 1 and used it here, it is also ok) V2=nR(T2)/p ext w = - p ext (V2 - V1)...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
