Vocabulary
100
Water and our bodies.
What are two objects that absorb energy from the sun?
100
An object that can transfer heat easily.
Define thermal conductor.
100
It is when object heats or contracts due to climate changes.
What is thermal expansion and contraction.
100
The energy that all moving object posses.
What is the definition of kinetic energy?
200
It commonly travels through empty space.
How does radiant energy commonly travel?
200
The uneven heating of liquid on a stove.
What can produce convection currents?
200
An example would be metal.
What is an example of a thermal conductor?
200
Concrete expands in the summer but contracts in the winter.
What is an example of thermal expansion and contraction>
200
It is the transfer of heat by two objects that are touching.
What is the definition of conduction?
300
It travels in the form of magnetic waves.
In what form does radiant energy travel?
300
Volcanic eruptions.
What geological event occurs because of convection currents in magma?
300
It would overflow because the liquid would expand due to hot weather.
What might happen to the car engine if you fill it to the brim on a hot day.
300
The transfer of radiant energy in the form of electromagnetic waves.
What is the definition of radiation?
400
Because they are absorbed by the Earth's atmosphere.
Why don't solar rays, such as ultra violet and gamma rays, reach the Earth's surface?
400
Thunderstorms, clouds, and thunderheads.
What are three natural processes that depend on convection?
400
The hot object's particles collide with the cold object and in doing so they heat the cold object.
What happens when a cold object touches a hot one?
400
It would crumple up because the air in contracting due to the cold weather.
What happens to a balloon if you bring it outside in the winter?
400
The increase of volume of an object that is heated.
What is the definition of thermal expansion?
500
It reflects most of the light because it is white and smooth.
Why does snow reflect most light?
500
It feels cooler because the energy from the Sun does not heat the air over land and water evenly.
Why does the air feel cooler near lakes and oceans in the summer?
500
Pots, pans, and stoves.
Name some good in real life conductors we use every day.
500
They should because they could burst due to the temperature.
Why should car tires be inflated according to the manufacturers recommendations?
500
The transfer of thermal energy from one part of a fluid to another by a circulating vent of faster and slower particles.
What is the definition of convection?
