00:03 Hi there.

00:04 In this question, we have three different scenarios, and we want to know what happens to the volume of a gas sample.

00:17 Let's look at the first scenario.

00:20 In letter a, the temperature increases at constant pressure.

00:24 Well, this is described by charles law.

00:30 And charles law is the gas law that says when number of moles and pressure are temperature are, i'm sorry, number of moles and pressure are constant, the volume, and the absolute temperature are directly proportional.

00:57 This means that if the temperature increases, then the volume increases.

01:10 And we want to select the drawing that shows a larger volume.

01:14 Well, that would be diagram number three.

01:24 All right, so diagram number three would be what happens when the temperature increases at constant pressure.

01:32 The volume would increase.

01:35 Let's look at letter b.

01:37 In letter b, the pressure increases at constant temperature.

01:43 So this was going to be boyle's law.

01:47 Boyle's law describes the relationship between pressure and volume when the number of moles and temperature are constant.

01:55 Boyle's law says that pressure and volume will be inversely proportional...
