HW-98
Use the following words to make your flashcards. Spend at least 15 minutes every night
looking over them.
Atom: the smallest part of an element that still has the properties of that element
Atomic Number: The number of protons in that atom.
Atomic Mass: The number of protons and neutrons in that atom.
Molecule: The smallest part of a compound that still has the properties of the compound
Compound: Two or more atoms or elements chemically combined together. Compounds can only
be separated by chemical means. Compounds always have a chemical formula.
Mixture: Two or more elements, molecules, or compounds in the same area but not chemically
attached. Mixtures can be separated by physical means.
Melting Point: a unique property of every metal, a way to identify metals. It is the point at which a
solid turns into a liquid.
Boiling Point: a unique property of every liquid, a way to identify liquids. It is the point at which a
liquid turns into a gas.
Physical Change: change the shape or structure, but the object is still the object. Physical changes
can be reversed.
Chemical Change: changes the chemical structure and creates something new. Signs include
bubbles or heat given off. This cannot be reversed.
Speed formula: Speed = Distance
Time
Speed Formula Triangle:
Kinetic Energy: the energy of an object in motion (an object that is moving)
Potential Energy: stored energy in an object. An object that is not moving has potential energy.
Heat transfer: The movement of heat from one object or place to another. Heat moves from hot to
cold.
Radiation: the transfer of heat energy through electromagnetic waves
Conduction: the movement of heat energy through a solid
Convection: The movement of heat energy in a circular motion through a liquid or gas
