Energy Vocab

Specific Heat

• A method of heat transfer through solids. Heat transfer that is caused by the collision of atoms in solids.

• The amount of heat required to change the temperature of one gram of a substance 1° C without a change in phase. The heat capacity of a material.

• Evaporation. The change in phase or state from a liquid to a vapor (gas). Evaporation of water is a cooling process

• Stored energy or energy of position.

Absolute Zero

• Zero (0) on the Kelvin scale. The temperature at which there is no heat in an object. The random motion of particles stops.

• Energy of motion. The kinetic energy of a particle or system is proportional to the product of the mass and square of the velocity.

• A method of heat transfer in liquids and gases (fluids) that involves density differences and produces a circulation pattern within the fluid.

• The change in phase of a substance, such as water, from a liquid to a solid. The substance must release energy for the change to occur.

Conduction

• The change in state of matter from a vapor to a liquid. Condensation of water vapor during cloud formation releases large amounts of energy to the atmosphere.

• A method of heat transfer through fluids such as air or water. The circulatory motion that occurs when different areas of a fluid are at different temperatures. The motion results from the variation of density of the fluid and the action of gravity.

• A method of heat transfer through solids. Heat transfer that is caused by the collision of atoms in solids.

• Energy of motion. The kinetic energy of a particle or system is proportional to the product of the mass and square of the velocity.

Convection

• A method of heat transfer in liquids and gases (fluids) that involves density differences and produces a circulation pattern within the fluid.

Joule

• Jewelry- diamonds, rubies, sapphires

• unit of energy

• unit of heat

• unit of nothing

Gamma rays

• Rays from the sun

• Electromagnetic waves with zero frequency

• Electromagnetic waves with the longest wavelengths and lowest frequencies

• Electromagnetic waves with the shortest wavelengths and highest frequencies

Electromagnetic Spectrum

• Electromagnetic waves with the longest wavelengths and lowest frequencies

• Electromagnetic waves with the shortest wavelengths and highest frequencies

• An object that gives off electromagnetic energy

• A method of classifying radiation on the basis of wavelength and frequency. The continuous listing of wave energy from the shortest wavelengths and highest frequencies (gamma rays) to the longest wavelengths and lowest frequencies (electric waves). The energy of the wave is directly proportional to its frequency.

Phase change

• Change in state of matter. The addition or removal of heat energy can cause the form of matter to change between solid, liquid, and vapor

• The change in state from a solid to a liquid

• The change in phase of a substance, such as water, from a liquid to a solid. The substance must release energy for the change to occur.

• Evaporation. The change in phase or state from a liquid to a vapor (gas). Evaporation of water is a cooling process
