An electron is in the ground state of an infinite well (a box) where its energy is 5.00 eV. In the next higher level, what would its energy be? (1 eV = 1.60  10-19 J)
 
  A) 1.25 eV B) 10.0 eV C) 15.0 eV D) 20.0 eV E) 2.50 eV

Question 2

A solid object has a volume density 0 at a temperature of 315 K. The coefficient of volume expansion for the material of which it is made is 7.00  10-5 K-1.
 
  What will be its density (in terms of 0 at a temperature of 425 K, assuming that it does not melt and that its thermal properties do not change with temperature?
