Science Energy 3

What is energy?

• The movement of particles from an area of high concentration to an area of low concentration

• The measure of the average kinetic energy of the particles in a material

• The transfer of thermal energy from a region of high temperature to a region of low temperature

• The ability to cause a change

What is kinetic energy?

• Energy an electric current carries

• Energy that sound carries

• Stored energy due to the interactions between objects or particles

• Energy due to motion

What is potential energy?

• The sum of potential and kinetic energy in a system of objects

• The ability to cause a change

• Stored energy due to the interactions between objects or particles

• The transfer of energy that occurs when a force makes an object move in the direction of the force

What is work?

• The study of heat

• The measure of the average kinetic energy of the particles in a material

• The process of changing energy from one form to another

• The transfer of energy that occurs when a force makes an object move in the direction of the force while the force is acting on the object

What is the difference between condensation and vaporization?

• The movement of particles from an area of high concentration to an area of low concentration

• The sum of potential and kinetic energy in a system of objects

• The process by which a gas turns into liquid and the change in state from liquid to gas

• The transfer of thermal energy from a region of high temperature to a region of low temperature

Where does evaporation occur?

• Occurs throughout the liquid

• Occurs when a gas turns into liquid

• Occurs when a liquid turns into gas

• Only occurs at the surface of a liquid

What happens when the temperature is high?

• The higher the temperature, the greater the movement of particles so the greater the kinetic energy

• The lower the temperature, the greater the movement of particles so the greater the kinetic energy

• The lower the temperature, the lower the movement of particles so the lower the kinetic energy

• The higher the temperature, the lower the movement of particles so the lower the kinetic energy

What are the three heat transfer methods?

• Heat, work, energy transformations

• Diffusion, thermodynamics, temperature

• Potential energy, kinetic energy, mechanical energy

• Conduction, convection, radiation

What is friction?

• The energy an electric current carries

• The sum of kinetic and potential energy of the particles that make up an object

• A force that resists the sliding of two surfaces that are touching

• The transfer of thermal energy from a region of high temperature to a region of low temperature

What is waste energy?

• The thermal energy that cannot be used when it is released

• The sum of potential and kinetic energy in a system of objects

• The energy due to motion

• The stored and released energy in the nucleus of an atom
