Re: Heat Capacity
Heat capacity is the amount of heat needed to change the temperature of an object by 1 degree Celsius. The difference with specific heat is the heat needed to change 1 GRAM of object by 1 degree Celsius.

from the midterm booklet
The energy required to break a C-C bond in a molecule is 348 kj*mol^-1.
will visible light be able to break this bond? If yes, what is the color of that light?
If not, what type of electromagnetic radiation will be suitable?
Why is Avogadro's number involved in the process of solution?

Re: Kinetic Energy of Electrons [ENDORSED]
when doing photoelectric experiments, it is important to keep in mind the kinetic E- formula.
Photon- Energy moved = E(k)
so whatever the excess energy is, will be kinetic energy ( 1/2 mv2 ) of a single atom
i hope this helps!
