1.3 Equilibrium and Energy

Question 1

First Law of Thermodynamics

Answer 1

Energy cannot be created nor destroyed

Question 2

Second Law of Thermodynamics

Answer 2

Entropy of an isolated system always increases

Question 3

Entropy

Answer 3

A measure of disorder in a system

Question 4

Stable Equilibrium

Answer 4

An equilibrium that returns to normal after something is displaced

Question 5

Steady State Equilibrium

Answer 5

there are inputs and outputs of energy and matter, but the whole system remains relatively constant

Question 6

Negative Feedback Loop

Answer 6

Stable - they tend to neutralize or counteract any change away from the equilibrium.

Question 7

Positive Feedback Loop

Answer 7

Unstable - they tend to amplify changes and drive the system towards a tipping point

Question 8

Resilience

Answer 8

The amount of disorder that an ecosystem can effectively manage

Question 9

Tipping Point

Answer 9

the point at which a series of small changes or incidents becomes significant enough to cause a larger, more important change.
