**Homework Statement::**First of, this is not a "homework" per say, since this is not in my curriculum. If you still want to help, see the description :)

**Relevant Equations::**C = Q/(delta T), where delta T is the raise in temperature in Kelvin and Q is the added heat energy

I want to learn about heat capacity. What I know, is that heat capacity is the relationship between added heat and the raise/ fall in temperature.

See "Relevant Equations" for the equation.

My understanding of heat capacity is - without repeating myself again - is, that different objects have different heat capacity. As an example, if you rub the palms of your hands (assuming you have two pair of hands), you will more quickly get your hands hot than, let's say, a metal rod.

So, with this basic out of the way, here comes the very "silly" question. How come, our "hands" are getting warmer more quickly than the metal rod?

That "heat" I am experiencing when rubbing my hands, if we joyfully imagine reaches 100 degrees celsius, would that mean, that it would take less time for my hands to reach 100 degrees than a metal rod? Furthermore, with a more "normal" experiment. If I placed both my hand and a metal rod in 100 degrees celsius boiling water, would my hands reach 100 degrees celsius faster than the metal rod? Evenmore, does this also mean, that we need more Joule to heat up 1 degree of celsius?

This is the fundamental question I am so eager to be enlightened about. I therefor hope I have the "correct" way of understanding heat capacity. Furthermore, sorry in advance if I am missing some physics terms.
