Energy, energy cycles, organism organization Flashcards
the ability to do work (including heating)
energy
Forms of energy
Kinetic energy and potential energy
Energy due to motion
Kinetic energy
thermal energy
microscale
rigid body motion
macroscale
Energy that is stored, and may eventually be released
potential energy
chemical energy
microscale
gravitational energy
macroscale
study of how energy is transferred
Thermodynamics
energy is conserved, neither created nor destroyed, can only be recycled
1st law
each energy transfer reduces the amount of energy available to do work
2nd law
Entropy (i.e., chaos/disorder)
tends to increase in all natural systems so, we need a constant input of energy to maintain life.
Main transfer processes
work and heat
applying a force over a certain distance
work
energy transferred between objects of different temperature
heat
