Structure & Properties of Matter
This describes anything that has mass and occupies space.
What is matter?
This number represents the number of protons in an atom.
What is atomic number?
This is the energy of motion.
What is kinetic energy?
This law explains that energy cannot be created or destroyed.
What is the Law of Conservation of Energy?
This is a push or pull on an object.
What is a force?
This is the smallest unit of an element that retains its properties.
What is an atom?
Elements in this part of the periodic table share similar properties because they have the same number of valence electrons.
What is a group (column)?
This is stored energy based on position.
What is potential energy?
This occurs when energy changes from one form to another.
What is energy transformation?
This occurs when forces are equal and do not change motion.
What are balanced forces?
This forms when two or more atoms chemically bond together.
What is a molecule?
This law states that matter cannot be created or destroyed in a closed system.
What is the Law of Conservation of Matter?
This type of heat transfer occurs through direct contact of particles.
What is conduction?
This form of energy is produced by moving electrical charges.
What is electrical energy?
This occurs when forces are unequal and cause a change in motion.
What are unbalanced forces?
This type of mixture has visibly different components, such as sand and iron filings.
What is a heterogeneous mixture?
This type of substance is made of only one kind of atom.
What is an element?
This type of heat transfer occurs through the movement of fluids like air or water.
What is convection?
This form of energy is associated with the vibration of particles and can be felt as heat.
What is thermal energy?
This force opposes motion between two surfaces in contact.
What is friction?
This type of change results in the formation of a new substance with different properties.
What is a chemical change?
This type of pure substance is made of two or more elements chemically combined.
What is a compound?
This type of heat transfer occurs through empty space without a medium.
What is radiation?
This explains how potential energy converts to kinetic energy as an object falls.
What is energy transformation (potential to kinetic)?
This is the tendency of an object to resist changes in motion.
What is inertia?
