Energy test
We recently had a test over energy and phase changes. I did decent on the test with an 85%. I was hoping for a little higher, but I'm content with that. I had a pretty good understanding of the phase change graph and transfer of energy between phases. So here's some cool pictures relating to this unit.
Energy
We have moved on to our next unit of energy. This unit seems to be easy so far and we only have two lectures. Our first lecture was about energy in relation to the movement of energy in a substance.
We use and equation Q=mcT where Q is energy, m is mass, c is specific heat, and T is change in temperature. This equation can be used also to relation two substances to each other if you use mcT=mcT.
