Unit 2 Test
Energy in Forms
-
-
Potential Energy- Energy that an object has due to its position, condition, or chemical composition
-
-
Sound energy- energy caused by vibration of particles in a medium such as steel, water, or air
-
-
Chemical Energy- form of potential energy; amount of chemical energy in a molecule depends on the kinds of atoms and their arrangement; sources of chemical energy are your food you eat
Thermal Energy- object is the kinetic energy of its particles; Higher temp, particles move faster
-
-
-
Mass increases, Kinetic Energy increases
-
Heat is measured 2 ways; Calorie; amount of energy needed to raise the temp of 1 gram of water by 1 degree Celsius and Joules
-

-
-
-
Nonrenewable Source- energy source that can not be produced, grown, or restored as fast as it is used
-
-
-
Natural Gas- gases that become trapped in rock formations, half of U.S. uses natural gas to heat home; produces carbon dioxide
Petroleum- "rock oil"; mined on land or in ocean; separated into fossil fuels such as gasoline, diesel, and jet fuel

-
Average Kinetic energy decreases, than temp decreases
-
Energy from burning Biomass- renewable; recently dead organic material that can be used as fuel; burning them releases carbon dioxide
-
-
-
-
-
Hydroelectric Energy- renewable; powered by water cycle; can only be produced by large amounts of water
