energy transferred when a change in temperature occurs
heat
the ability to generate heat or do work
energy
energy transferred when force is applied to produce a change in position
work
si unit is
joules (j)
energy of movement
kinetic energy
energy stored because of the physical position or chemical composition of the substance
potential energy
energy stored in chemical bonds
chemical energy
energy due to random movement of particles
thermal energy
measurement of the average kinetic energy of particles
temperature
area of the universe where the reaction or physical change takes place
system
everything in the universe outside of the system
surroundings
energy cannot be destroyed or created
law of conservation of energy
transfer of heat due to the collision of particles
conduction
transfer of energy due to the flow of fluids at different temperatures
convention
transfer of energy due to electromagnetic waves (no physical contact)
