THERMODYNAMICS AND ENERGY
Thermodynamics: The science of
energy.
Energy: The ability to cause changes.
The name thermodynamics stems from
the Greek words therme (heat) and
dynamis (power).
Conservation of energy principle:
During an interaction, energ

ENERGY AND ENVIRONMENT
The conversion of energy from one form to another
often affects the environment and the air we breathe in
many ways, and thus the study of energy is not
complete without considering its impact on the
environment.
