The total kinetic energy of tiny particles that make up matter is –
thermal energy
The transfer of thermal energy that occurs in solids, liquids and gases when two substances of different temperatures touch.
conduction
Regarding thermal energy, the faster the tiny particles of matter move, the colder the matter becomes. (True or False)
False
The transfer of thermal energy from one place to another by the movement of fluids, which occurs on a large scale in atmospheric gases, occeans and earth’s mantle.
convection
The energy transferred between two objects of different temperatures.
heat
What law states that energy can neither be created nor destroyed, energy just changes form?
the law of conservation of energy
What type of current creates a cyclical motion that occurs because the density of a fluid is related to its temperature, causing sinking and rising of the fluid, creating a circular pattern..
convection curent
The transfer of energy by electromagnetic rays which may occur in empty space.
radiation
Give an example of conduction.
Any answer that shows the transfer of heat by direct contact.
Conduction between two objects can only occur when –
both objects are in physical contact with each other
The average kinetic energy of all the particles in a material, measured by a thermometer in degrees.
temperature
True or False: Heat transfer happens when some energy moves from one object to another object.
True
Heat energy is transferred to a beaker of water on a heated hot plate by –
Conduction
Potatoes that are boiled in water receive thermal energy through –
Convection
True or False: The transfer of heat energy that moves through empty space is conduction.
False
One example of radiation is when –
Any answer that shows the transfer of energy by electromagnetic rays which may occur in empty space.
