Unit 3, Lesson 6

This was quite a gassy lesson!
...No...? Oh, alright. Moving on...

We discussed Charles' Law. Charles' Law simply states that the volume and temperature of a gas sample are proportional to each other through the use of a constant, which we represent as a lowercase k. The equation for finding the constant, k, the volume, or the temperature of a sample is as follows:

V= kT

k = V/T

T = V/k

The proportionality constant varies depending on the size of the sample of gas that you have. 

Problems:

1.) Explain how to find the proportionality constant for a sample of gas. If you know that you can find volume by multiplying k and the temperature of your sample, you can scramble the equation (which I have so graciously done above) and divide volume by temperature to get your constant.

4.) A sample of gas in a cylinder has a volume of 980 mL at a temperature of 27 degrees Celsius. If you allow the piston to move while you heat the gas to 325 K, what will the volume of the gas be at 130 degrees C?

27 degrees C = 300 K. 130 degrees C = 403

980/300 = 3.26 

403(3.26) =  123.6 or about 124 mL
