Unformatted text preview: Group4 Review thermodynamics: 4 Laws of Thermodynamics:
Zeroth Law- defines the concepts of thermal equilibrium and temperature 1St Law- Conservation of energy (with heat) 2"Id Law- the entropy in the universe always increases in the long run entropy— a measure of the disorder in a system
log + fire ® heat + ash order xl/ disorder
The universe is more disordered even though you create a little bit of order. You still create more disorder. (ex:
making a house of cards)
The more ordered a system is, the more disorder you introduce in the environment. There is also a way to produce disorder , but y0u have to produce a lot of energy (from outside) \l/ order
H 9 He=> heat + "nuclear ash” Heat is a byproduct for putting order into the disorder. Bottom line of 2"“I Law- the sun can also die.
The inevitable- everything will go back to its lowest energy state. 3” Law- Can’t reach absolute zero in a finite number of steps Absolute zero— state of zero atomic and molecular motion
Ch. 8: (Transition from Classical to Modern Physics)
Classical physics 1. Newtonian mechanics
2. Electromagnetic theory
3. Thermodynamics 4. Theory of turbulence Maxwell’s equations give you a prescription for how electric and magnetic fields produce each other ...
