Types of Energy
This is the type of energy found in electrical wires.
electrostatic/electric/electical
What are some uses of electrostatic energy (electrical)?
heating a house, lighting a house, a clock, etc.
What's the name of this law"
"Energy can be stored or transferred but never created or destroyed."
This is the name of a branch of science. It studies the behavior of the universe.
Physics
What's the smallest state in America?
Rhode Island
This is the type of energy stored in food.
Name TWO non-renewable sources of energy.
coal, oil, natural gas
What is thermal expansion?
This occurs when particles move faster in a substance and cause the substance to expand.
Name TWO forms of energy in a roller coaster.
kinetic, electrical, gravitational potential, heat, etc.
How many bones do sharks have?
0 (only cartilage)
This is the type of energy in an atomic bomb.
nuclear energy
Name THREE renewable energy sources.
wind, solar, biofuel, hydroelectric
Why do some substances heat up faster than others?
Some substances have a lower thermal capacity (EX) oil has a lower thermal capacity than water
Name an example of elastic potential energy.
How was the 16th president of the United States?
Abraham Lincoln
This is the energy of movement. An example is a roller coaster traveling at top speed.
kinetic
How can radiation be used for practical purposes?
carbon dating, cancer treatment, radiology, irradiation (keep food from spoiling)
What's conduction?
It is the heat transfer in solids.
Explain why water can freeze or turn into a gas.
Because of thermal expansion, when water is heated up, its particles move faster and faster until the water expands and the particles turn into water vapor and rise due to convection. Water can freeze when it loses heat and the particles slow down so much that the water turns into a solid substance (ice).
In what movie will you find character who are looking for a brain, a heart, and courage?
The Wizard of Oz
This type of energy generates heat. An example is fire.
thermal
It is a method of measuring how old a dead organism is. It occurs when scientists measure the ration of carbon 12 to carbon 14 in the dead organism. The carbon 14 is radioactive and therefore leaves the organism. In other words, it is measuring how much carbon 14 has left the decaying organism.
What is convection?
It is the process of heat transfer in liquids and gases.
In a lake there are pockets of cold and warmer water. Where would you generally find the colder pockets? Where would you generally find the warmer pockets? Why is this?
Who was the first man to step foot on the moon?
Neil Armstrong
