3. IMPORTANT FUNCTION
Heating & Cooling - BASICS
CONDUCTION: transfer
of energy through solid matter
from particle to particle
CONVECTION: transfer of
heat energy through a gas or
liquid by movement of currents
RADIATION:
electromagnetic waves which
directly transport heat energy
through space
EVAPORATION (not true heat transfer but very useful): when a liquid changes
to a gas it uses up heat and in doing so, cools an object or a liquid in contact with it
