the energy that an electric current carries
What is electric energy?
a scientific law stating that energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed
What is the Law of Conservation of Energy?
the energy that electromagnetic waves carry
What is Radiant Energy?
the transfer of thermal energy due to collisions between particles
What is CONDUCTION?
a device that converts electric energy into thermal energy
What is a Heating Appliance?
a material through which thermal energy flows quickly
What is Thermal Conductor?
the ability to cause change
What is energy?
the total energy of an object or group of objects due to large-scale motions and interactions
What is Mechanical Energy?
an energy resource that is replaced as fast as, or faster than, it is used
What is Renewable Energy Resource?
the transfer of thermal energy by the movement of particles from one part of a material to another
What is CONVECTION?
the transfer of thermal energy by electromagnetic waves
What is RADIATION?
a decrease in a material's volume when the temperature is decreased
What is Thermal Contraction?
the remains of ancient organisms that can be burned as an energy source
What is a fossil fuel?
an energy resource that is available in limited amounts or that is used faster than it is replaced in nature
What is Nonrenewable Energy Resource?
the energy that sound carries
What is Sound Energy?
the movement of fluids in a cycle because of convection
What is Convection Current?
a device that uses electric energy to pump thermal energy from a cooler location to a warmer location
What is a Refrigerator?
a device that regulates the temperature of a system
What is a thermostat?
a force that resists the motion of two surfaces that are touching
What is FRICTION?
energy that is stored in the nucleus of an atom
What is Nuclear Energy?
energy due to the motion of particles that make up an object
What is Thermal Energy?
the movement of thermal energy from a region of higher temperature to a region of lower temperature
What is HEAT?
the amount of thermal energy it takes to increase the temperature of 1 kg of a material by 1ºC
What is Specific Heat?
an increase in a material's volume when the temperature is increased
What is Thermal Expansion?
energy due to motion
What is Kinetic Energy?
stored energy due to the interactions between objects or particles
What is Potential Energy?
the transfer of energy that occurs when a force is applied over a distance. Work is only being done while the force is applied to the object
What is WORK?
a machine that converts thermal energy into mechanical energy
What is a Heat Engine?
the measure of the average kinetic energy of the particles in a material
What is the temperature?
a material through which thermal energy flows slowly
What is Thermal Insulator?
