Energy

Thermodynamics

The study of energy and energy transfer in physical matter

System

Matter being effected by energy

Open System

System in which energy can be exchanged with its surroundings

Closed System

System in which energy is not exchanged with it’s surroundings

First Law of Thermodynamics

Energy cannot be created or destroyed

Second Law of Thermodynamics

Some energy is lost as an unusable form, heat, in every transfer

Entropy

Measure of randomness in systems

Kinetic Energy

Energy of moving objects

Potential Energy

Energy stored in an object

Chemical Energy

Potential energy in chemical bonds

Free Energy

Usable energy in chemical reactions

Exergonic

Release of free energy, spontaneous

-🔺G

Exergonic

Endergonic

Absorption of energy, requires free energy to take place

+🔺G

Endergonic

Activation Energy

Small amount of energy input required for a chemical reaction to occur
