Plot per capita energy use for the five countries in Problem 8-4 on the y-axis, and energy intensity on the x-axis. Does the position of the country data points make sense? Explain why or why not.
What will be an ideal response?
Yes, this makes sense. Per capita energy use generally reflects the level of average wealth and income in a nation, which is also a reflection of its overall level of economic development. Energy intensity will reflect its level of industrialization, economic development, structure of the economy, and level of economic efficiency. Australia and Germany are highly industrialized, wealthy nations. Kenya is the poorest, and Mexico and China continue to industrialize. Mexico probably has a lower energy intensity than China because its industrial mix is different, and it is more energy efficient.

Answer the following statement(s) true (T) or false (F)
1. Hydronic heating systems should never use a combination of flexible and rigid piping materials. 2. In the absence of any building or mechanical codes that require otherwise, type M is the standard for copper tubing used in hydronic heating systems. 3. Plumbing codes no longer allow solders containing lead to be used for domestic water service. 4. The molecular structure of nonmetallic tubes such as those made of PEX or rubber compounds is such that oxygen molecules can diffuse through their tube walls and be absorbed by the fluid within. 5. The pressure difference between the inside and outside of the tube has a very strong effect on oxygen diffusion.
