Question | Answer |
A theory that defined thermal energy as an substance that flowed from hot bodies into cold bodies. | caloric theory |
The flow of thermal energy from a hotter to a cooler object by direct contact. | conduction |
The flow of thermal energy from one place to another by the movement of particles. | convection |
The amount of thermal energy an entire object must gain or lose to change its temperature 1 °C. | heat capacity |
The absolute temperature scale, whose theoretical zero point is absolute zero. Its single fiducial point is the triple point of pure water (273.16 K); one kelvin is the same size unit as one degree Celsius. | Kelvin scale |
The amount of thermal energy absorbed per gram as a solid melts (fuses) at its melting point. The same amount of heat per gram must be released to freeze the substance. | latent heat of fusion |
The amount of thermal energy absorbed per gram as a liquid vaporizes. The same amount of heat per gram must be released to condense the vapor to a liquid. | latent heat of vaporization |
Nuclear particles or electromagnetic waves that radiate away from their sources; a method of heat transfer through radiant(electromagnetic) energy. | radiation |
The amount of thermal energy needed to raise or lower the temperature of 1g of a substance 1 C. | specific heat |
A temperature scale with fiducial points at the freezing point (0 °C) and the boiling point (100 °C) of pure water at 1 atm of pressure. | Celsius scale |
A temperature scale with fiducial points at the freezing point (32 °F) and the boiling point (212 °F) of pure water at 1 atm of pressure. | Fahrenheit scale |
Law stating that every natural process proceeds toward a condition of lowest usable energy and highest entropy. | second law of thermodynamics |
A quantity of thermal energy that flows from one system to another | Heat |
The measure of the average kinetic energy in a material | Temperature |
The study of thermal energy, heat, and their useful applications. | Thermodynamics |
