Radiation, Convection, Conduction
The direct transfer of heat from one substance to another substance that it is touching. What is it?
Conduction
What is mechanical energy?
the amount of work an object can do because of the object's kinetic and potential energies.
What is heat?
The energy transferred between objects that are at different temperatures.
What is the diffrence between a isulator and a conductor?
In a conductor, electric current can flow freely, in an insulator it cannot.
What is Radiation?
Energy that is radiated or transmitted in the form of rays or waves or particles.
What is potential energy?
stored energy that results from the position or shape of an object.
What is temperature?
A measure of the average energy of motion of the particles of a substance.
What is a conductor?
Conductors are materials that permit electrons to flow freely from particle to particle.
The transfer of thermal energy by the circulation or movement of a liquid or gas. What is it?
Convection
What is kinetic energy?
the energy of motion.
True or False. Heat and temperature are the same.
False
What is a isulator?
A material that does not easily transmit energy, such as electric current (see also current) or heat.
What is an example of radiation, convection, and conduction?
A pot of boiling water on a stove.
What is Energy?
ability to do work.
What is the difference between heat and temperature?
Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules.
True or Fasle. A plastic water bottle is a insulator.
True
What do radiation, convection, and conduction all have in common?
They are all the transfer of thermal energy.
If you have a 4-inch cup with 100 degrees F and a 1 ft cup that is 70 degrees F which has more energy?
(both cups filled up to the top.)
