m=CΔt

After we were done with all of the biodiesle projects, we started on a unit focused on energy. During this unit we will be looking at numerous systems and determining how the energy flows in and out of the system.

There are two different types of systems, endothermic and exothermic. Endothermic reactions gain energy from the surroundings, with a net energy gain. Exothermic reactions loose energy to their surrounding , with a net energy loss.




Next we leaned about how to calculate heat using a formula that looks like M-Cat. m=CΔt allows you calculate change of heat, mass of sample, amount of heat, or temperature

. 

c is specific for a certain material, for example c for water is 4.186, while the specific heat capacity for copper is .385.
