Chemical Properties
Define Potential energy.
Stored energy
Define and give an example of radiation.
Heat is transferred through space, sunlight or fireplace
What does the Law of Conservation of Energy state?
Energy can neither be created or destroyed, it can only be transferred.
Which two phases of matter take the shape of their container?
Liquids and Gases
A new substance is formed or a permanent change occurs during this process.
Chemical Change
List at least 5 other forms of energy.
Mechanical
Chemical
Nuclear

What is the difference between conduction and convection.
Conduction= heat is transferred through objects touching
Convection= heat is transferred through fluids
Define Heat.
transfer of thermal energy because of a difference in temperature
What does the kinetic theory of matter state?
All matter is made of tiny particles called atoms which are in constant motion
Define Endothermic or Exothermic reactions.
Endothermic= heat is absorbed
Exothermic= heat is released
