HEAT VERSUS TAMPERATURE
- Heat is random motion of molecules
- Average speed of motion= heat
- Molecules are moving, this means they bounce off of us. A comfortable
temperature is when there is just the right amount of collisions.
SECOND LAW OF THERMODYNAMICS
USABLE ENERGY- direction and movement
TENDS TO- usually probable, not just possible become
UNUSABLE- random movement with no specific pattern with
USE- collisions, directionally moving particles become less directional
CAN HEAT EVER CONTAIN USUABLE ENERGY
- Even though heat has unidirectional motion, if the unidirectional motion is
pushing at less pressure (colder air) it can create motion.
