B. A 200 g object with a volume of 100 cubic centimeters

C. A 100 g object with a volume of 100 cubic centimeters

D. A 400 g object with a volume of 50 cubic centimeters

Rank the following in terms of increasing pressure:

2. Consider four blocks with identical volumes placed in water as shown below.

Which block has the smallest buoyant force on the water and why?

3. Consider four blocks with identical volumes placed in water as shown below. Rank the blocks in terms of increasing density:

4. Consider a tall container filled with water. There are three holes of equal size in the side of the container as shown on the diagram below. The red arrows indicate the velocity of the water as it flows out of the holes.

Why is the velocity larger for the bottom stream of water?

5. On a quiet day, the atmospheric pressure results in a force of about 10,0000 N on a window pane with an area of 1 square meter.

a. Why does this large force not shatter the window?

b. How will this change if a strong wind is blowing across the window pane?

6. Explain why locations near a large body of water generally have higher average temperatures in the winter and lower average temperatures in the summer.

7. A mirror cleaned with an alcohol solution is slightly colder right after it is cleaned. Why?

8. To keep the canned food from freezing in a storage cellar, a farmer places a tub of water in the cellar. Explain.

9. Why is it safe to stick your tongue on a wooden pole on a cold winter day, but not on a metal pole?

10. You are in the frozen food section of the grocery store and you notice that your hand gets cold when you place it on the glass windows of the display cases. Your friend says this is because coolness is transferred from the display case to your hand. What do you think?

11. Why are good conductors of electricity usually also good conductors of heat?

12. Why is it cooler to wear a white shirt than a black shirt on a hot, sunny day?

B. A large number of atoms move from one place to another

C. Electrons collide with other electrons and with atoms.

D. Electromagnetic waves travel though space to heat up an object.

23. Heat transfer by convection occurs when:

A. Atoms give off energy in the form of radiation

B. A large number of atoms move from one place to another

C. Electrons collide with other electrons and with atoms.

D. Electromagnetic waves travel though space to heat up an object.
