Get Smart. 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
