thermal energy Flashcards
science
What is the definition of heat?
The flow energy from one object to another is called heat
In which direction does heat flow?
He always moves from a warmer object to a colder object
What is a conductor?
A conductors a material that easily transfers heat
What are some examples of a conductor?
Glass leaded, copper silver gold
What is an insulator?
An insulator is a material through which sheet does not transfer easily
What are some examples of an insulator?
Plastic cotton rubber wood
What are the three different methods that he can be transferred?
Radiation conduction convection
What is radiation?
Radiation does not require contact with any material for heat transfer to occur
What are some examples of radiation?
Sunlight heating the Earth, microwave heating food
What is convection?
Convection involves the use of fluids, gases, or liquid to transfer heat through a cycle
What are some examples of convection?
Water in a beaker on a hot burner. Bottom heats first, rises to the top, cool, and sinks down again.
What is conduction?
Con conduction requires direct contact for heat transferred to take place
What are some examples of conduction?
Bare feet on hot sand, metal spoon in hot soup
