List the four rules for sig figs?
1. All numbers 1-9 are sig figs
2. For numbers smaller then 1 find the first non-zero and count all the digits to the right
3. For numbers bigger then 1 start with first number and keep conting until you get to the last non-zero or a decimal point(place holders zeros are not sig figs)
4. For all numbers bigger then 1 with a decimal point they ALL are sig figs
500

What are the 4 main equations we use to measure heat energy, mass, spacific heat, and change in temperature?
Q= m x c x change in temp.
M= Q/ (c x change in temp.)
C= Q/ (m x change in temp.)
change in temp.= Q/ (m x c)
