Q1. Look up and list the following properties of the Sun:
A) Radius (give this in km)
B) Mass (give this in kg)
C) Surface Temperature (give this in Kelvin)
D) Central Temperature (give this in Kelvin)
E) Spectral Type
Be sure to Cite where you got the information!
Q.2. What is the difference between the surface temperature and the central temperature of the Sun? Where does all the nuclear fusion occur?
Q3. There are several spectral types for Stars: O,B,A,F,G,K,M (remember this by Oh be a Fine Guy/Gal Kiss Me!!!) List the major differences between O,B stars and K,M stars (compare and contrast lifetimes, temperatures, masses, and the numbers that we know about in our galaxy--aka which spectral type is more abundant and why?)
Q.4. Name two products that you use on a daily basis and do some research on the amount of energy or natural resources that each item consumes. Which of them is more energy efficient?
