ENERGY AND EQUILIBRIA Flashcards
What is energy?
It is the ability to do work. This ability is goverened by the laws of thermodynamics.
First Law of Thermodynamics
Energy can’t be created or destroyed it can only be transformed.
Second Law of Thermodynamics
The entropy of a system grows overtime.
What is Positive Feedback?
Enhance change in a system. they drive a ssytem away from its equilibrium and make it more unstable.
What is Negative Feedback?
Resist change in a system and draws the system back to its equilibrium. They keep the system stable.
What is resilience?
It is the ability of a system to go back to its equilibrium after disturbance. The more resistant to disturbance the more resilient.
Low reilience makes the system enter a new state= new equilibrium.
What are tipping points?
They are a critical threshold where even a small change can cause a significant disturbance to the system and cause a large response. Positive feedbacks drive systems to tipping points.
What is equilibrium?
A state of balance among the components in a system.
