Science Review Chapter 4 ● Energy: is the ability to cause change ● Kinetic energy: a moving object has because of its motion ● Potential Energy: energy is stored due to interactions between objects ● gravitational potential energy: is the energy due to gravitational force between objects ● Law of conservation: States that energy cannot be created or destroyed, it can only be transferred or converted. ● Calculate power Chapter 5 ● Temperature: Measure of the average kinetic energy of all the particles that make objects ● Thermal Energy: Sum of the kinetic and potential energy of the part ● Heat: energy that is transferred ● Conduction: Transfer of thermal energy by collisions ● Convection: transfer of thermal energy in a fluid by the movement of colder and warmer fluid from one place to another ● Radiation: transfer of energy by electromagnetic waves Chapter 14 ● Boiling Point: The point at which the pressure of the vapor of a liquid is equal to the external pressure on the surface of the liquid ● Melting Point: temperature at which a solid begins to liquify ● Plasma: is matter made up of positive and negatively charged particles ● What is plasma: Is similar to gas, but is highly e...
