Semiconductors

1.    Use MO theory to compare a semiconductor to an insulator and a conductor.

2.    What is an n-type semiconductor?  What element could you add to silicon to make an n-type semiconductor?

3.    What is a p-type semiconductor?  What element could you add to silicon to make a p-type seminconductor?

5.1

4.    Explain the source of the unit of pressure known as 'torr'.

5.    You should become familiar with the units of pressure presented on page 140.

5.2

6.    The equation for Boyle's law is PV = k.  Restate this in English.

7.    Charles' Law states that the volume of a gas at constant pressure is directly proportional to temperature; V = bT where b>0.  Explain why this relationship leads to the need to define the Kelvin scale of temperature.

5.3

8.  What is the value and units of R?  You should be aware that the units of P and V must match the units of R.  What units must be used for T?

5.4

9.    What is standard temperature?  What is standard pressure?

10.    How can one determine molar mass of a gas?

5.5

11.    How is mole fraction of a gas related to the partial pressure of a gas?
