Document Summary

Energy is a currency that can be spent to make things happen. Che 132 : prof. khalifa : lecture 1 - chapter 6 : thermodynamics and kinetics. The ability to do work is related to the difference in energy between the high energy and low energy states . Potential energy (pe) is a state function , which means the energy of an object depends only on the current state and not on how it got to that state. For instance , we don"t care how the boulder got above your head, we only care about how dangerous it is now that it is above your head. Kinetic energy (ke) is the energy of motion . Internal energy (e) - energy in a system. Make sure to change the sign of q and w accordingly! Calorie - energy needed to raise the temperature of 1 gram of water by 1 degree.
