[Lobcity]

Suppose the surface temperature of the Sun were about 18,000 K, rather than 6,000 K. How would the thermal radiation spectrum of the Sun be different?
 
  What will be an ideal response?

Question 2

Only low mass stars experience the temporary instability of the helium flash; high mass stars go directly into heavier element formation.
 
  Indicate whether the statement is true or false

Answer to Question 1

The higher temperature of the Sun would shift the peak of its thermal radiation spectrum from its current place in the visible light region into the ultraviolet. The hotter Sun would emit more energy at all wavelengths, with the greatest output coming in the ultraviolet.

Answer to Question 2

TRUE
