#### 8b tables

Here I introduce the tables of data that you'll need on this part of the course. I show the air, gas, liquids and solids tables and where they can be found in the LBoTF

#### 8e1 Examples of gas laws 1

Here I go through a first example of the use of the gas laws. This is to work out the mass of gas in a system.

#### 8b Ideal gas laws

Here I show the ideal gas laws. PV=mRT and P1V1/T1 = P2V2/T2. I also show how this can be applied to different gases using R=Ru/M

#### 8a Liquids, gases, and steam diagrams

Here I introduce liquids and gases. I go throught the processes whereby liquids turn to gases. I describe the regions on p-v and t-v diagrams.

#### 11d Some equations for entropy

I state that entropy is made out of that due to Irreversibility and that due to heat transfer, Q=TdS. Then I derive the entropy change for solids, liquids and ideal gasses.

#### 9c Specific Heat Capacities

Here I introduce isothermal processes. I then derive the specific heat capacities at constant volume and pressure. I reinforce that these can always be used to substiture for temperature. Finally I…

#### 10b Polytropic processes

Here I show that the polytropic process is a good way of describing changes in condition for closed systems with ideal gasses. I look at different values of the exponent, n. Then I calculate some at…
