Thermal Energy Vocabulary
What is heat?
The warmth that moves from something hot to something cold.
What is electricity?
A type of energy made by tiny moving particles called electrons. It flows through wires like water in a hose and can make things light up, move, or work.
What are the three main parts of a circuit
An energy source , Electrical load and a conductor
True or False: Plastic is a good conductor of heat ?
False its an insulator
What pair of inventors invented the light bulb ?
Thomas Edison and Lewis Latimer
What is temperature?
A way to measure how hot or cold something is.
What is a series circuit?
A circuit where electricity flows in one path. If one part stops working, everything turns off.
True or false: Metals are conductor of electricity and heat.
yes
True or false : Metal is a good insulator of heat.
No, metal is a conductor of heat.
Who is Nikola Tesla ?
Answers will vary : He was an inventor who worked with electricity and especially the Tesla coil.
What is an insulator?
Something that stops heat from passing through, like a jacket keeps you warm.
What is a parallel circuit ?
A circuit where electricity flows in more than one path. If one part stops working, the others can still work.
True or False: Plastic is an insulator of electricity and heat?
True
A spoon heating in a pot of boiling water is an example of _____________ .
A) Convection
B)Radiation
c) Conduction
C) Conduction
Why are conductors on the inside of a plug and insulators are on the outside ?
Answers will vary: Explain that conductors allow electricity to pass and insulators do not so this is how we make the wire safe.
What is a conductor?
Something that lets heat pass through easily, like a metal spoon in hot soup.
What is a closed circuit ?
A circuit that is complete, so electricity can flow and make things work.
How many paths for electricity to flow do series circuits have?
1
The hot sun shining on your face in bangkok in april is an example of _____________ .
A) Convection
B)Radiation
c) Conduction
B) Radiation
What would happen if you touched a conductor while a current is running through the circuit ?
You will be electrocuted :( as you will become a part of the circuit .
What is thermal energy ?
The energy that makes things warm or hot.
What is an open circuit ?
A circuit that is broken, so electricity cannot flow and nothing will work.
How many paths for electricity to flow do parallel circuits have?
2 or more
In hurricanes and tornadoes hot air rises and cold air falls this is an example of _____________ .
A) Convection
B)Radiation
c) Conduction
A) Convection
What will happen if you attach a piece of metal to a kite string (made of wool) and fly the kite during a lightning storm?
The key will be electrocuted and the sting will act as an insulator and protect you in theory do not try this like Ben Franklin did the inventor of the lightning rod.
