Chapter 22 At what temperature is the density of water the greatest? Chapter 23 What is the difference between a conductor and an insulator? Chapter 24 What is evaporation and condensation and what happens when it occurs?

200 Points Chapter 21 What is meant by saying that a thermometer measures it own temperature? Chapter 22 Why do lakes and ponds freeze from the top down rather than from the bottom up? Chapter 23 What is radiant energy? 23.3 Chapter 24 What is the difference between evaporation and boiling? 24.4

300 Points Chapter 21 What is heat and how is it calculated? Chapter 22 As you increase the temp. of a gas, what happens to the volume of the gas? What if you decrease the temp.? Chapter 23 Why does a good absorber of radiant energy appear black? 23.4 Chapter 24 How many calories are needed to melt 12 gram of water from 12 to 20 degrees C?

400 Points Chapter 21 Which has the greater amount of internal energy? An iceberg or a hot cup of tea? And which has a higher temp.? Chapter 22 If a gas is compressed, what happens to the temp. of the gas? And vice versa Chapter 23 Is a good absorber of radiation a good emitter or a poor emitter Chapter 24 What change in state occurred to make the dippy bird drink?

500 points Chapter 21 Why is the west coast of North America appreciably warmer in winter months than the east coast? Chapter 22 Would it be correct to say that tanks of compressed gas have higher temperatures than tanks of low-pressure gas? Chapter 23 What is solar and terrestrial radiation and are the wave lengths short or long?
