What is kinetic energy?
Name 1 factor that determines a substances thermal energy
kinetic energy
potential energy
mass
type of substance
the transfer of energy through direct contact
What is conduction?
the amount of heat needed to increase 1kg of a substance by 1C
What is specific heat?
What is absorbency?
occurs when a material's volume increases as particle motion increases
What is thermal expansion?
True or False: When a substance cools, it usually expands.
False
the transfer of energy among the particles of a fluid
What is convection?
A substance the allows the flow of heat
What is a conductor?
the change from a solid to a gas
What is sublimate?
the average kinetic energy of a substance
What is temperature?
the pull of particles to come together
What are attractive forces?
the transfer of energy through electro-magnetic waves
What is radiation?
A substance that does not allow heat to flow easily
What is an insulator?
the study of heat

Do insulators or conductors have high specific heat?
Insulators
the movement of particles from an area of high concentration to an area of low concentration
What is diffusion?
What causes the potential energy of a substance to increase?
an increase of space between the particles
when 2 substances in contact reach the same temperature
What is thermal equilibrium?
the transfer of thermal energy
What is heat?
Does water have high or low specific heat?
High Specific Heat
the movement of particles on all directions and at different speeds
