Solve the following problems on your own paper. Please:

Chapter 10

#4
Use formula 10.2 to help with this one.

#8
Note equation 10.3. Answer with 3 SF.

#10
Set up two equations with two unknowns (the final temp and final diameter).

#14
Answer with 3 SF. Use equation 10.6.

#20
The answer for the last part (you don't have to write this) is: "Accordion-like expansion joints at periodic intervals along the pipe."

#28
Be sure to use the proper version of R here. Answer with 2 SF.

#30
Answer with an integer, just drop any fractions you might come up with at the end.

#32
Assume N (or n) is constant throughout this problem, so V and T are changing, and you must calculate the new V to find density. Answer with 2 SF.

#4
Find the change in temperate first. Answer with 3 SF.

#6
Assume the heat difference is equal to the change in gravitational potential energy.

#10
You don't need to answer part (b).

#12
Find the total mass of lead needed, then divide by the mass of a single pellet to get the number of pellets. Answer with 3 SF.

#22
See the discussion on pages 360-1 for guidance. Answer with 2 SF.

#30
Example 11.7 will help here.

#32
This is mainly about keeping your units straight. To save you some time, the surface area of the house is 307 square meters.

#34
Work in mks units on this problem!

#40
The power is just equal to the heat loss (mL) from the melting ice. Use equation 11.6.
