Question | Answer |
Energy Transfer | Different forms of energy can be transferred from place to place by radiation, conduction, or convection. |
Heat Transfer | The transfer of thermal energy from one object to another. |
States of Matter | Can be in the form of solid, liquid, gas, and plasma. |
Conduction | The passing of heat through a material while the material itself stays in place. |
Convection | The flow of heat through a liquid or a gas, causing hot parts to rise and cooler parts to sink. |
Radiation | The giving off of infrared rays through space, like sun light. |
Kinetic Energy | The energy of any moving object. |
Potential Energy | Stored energy. |
Atoms | The smallest unit of an element that retains the properties of that element. The smallest particles that make up all matter. |
Molecules | A group of more than one atom joined together that acts like a single particle. A combination of two or more atoms. |
Mass | The amount of matter an object contains; measured in the unit grams on a triple beam balance. |
Closed System | A contained or isolated environment without influence or interaction with outside environments (like the inside of a sealed jar). |
Transformation | To change from one phase to another through the process of freezing, melting, boiling or condensation. |
Matter | Anything that has mass and takes up space. |
Mechanical Systems | An arrangement of parts that work together. |
Motion | The movement of molecules. This increases with temperature. |
Solid | A form of matter that has a definite shape and takes up a definite amount of space, like a book. |
Liquid | A form of matter that does not take up a definite amount of space and has no definite shape, like water. |
Gas | A form of matter that takes up a definite amount of space and has no definite shape, like air. |
Phase Change | Processes such as freezing, melting, evaporation (boiling point), condensation, are all examples of this. |
Plasma | State of matter that exists under the conditions of high temperature and pressure, like a star. |
Calorie | Unit of heat, defined as the amount of heat needed to raise the temperature of one gram of water one degree Celsius. |
Joule | The metric unit of work; equal to one Newton-meter. |
Melting Point | The particular temperature for each substance at which it changes state from a solid to a liquid. |
Boiling Point | The particular temperature for each substance at which it changes state from a liquid to a gas. |
Condensation | The changing of a gas into a liquid. |
Freezing Point | Also known as the melting point, that temperature at which a substance changes state, either from a liquid to a solid or from a solid to a liquid. |
Evaporation | The slow changing of a liquid into a gas. |
Sublimation | Change of phase from a solid to a gas. |
Proton | The positive charge in an atom |
Conservation of Energy | Energy can be transferred through radiation, convection, and conduction, but there is no net loss or gain of energy lost or gained in the transfer. |
Energy | The ability to do work or to make things change. |
Electron | The negative charge orbiting around the nucleus of an atom. |
Neutron | Found in the nucleus of an atom, this particle has no charge. |
Nucleus | The center of an atom, contains both protons and neutrons. |
