stored energy
Temperature is....
What are the processes of the water cycle? Start with evaporation.
- Evaporation
- Transpiration
- Condensation
- Sublimation
- Deposition
- Precipitation
- Infiltration
- Run-off
Define conduction, convection, and radiation
Conduction: flow of heat by direct contact
Convection: transfer of heat by mixing a fluid such as a liquid or gas
Radiation: transfer of energy in waves by electromagnetic radiation
Kinetic energy is
energy of motion
Transpiration is...
Finish the sentence:
As the temperature of the environment that water is in increases, then ______________________________.
The water's thermal energy also increases.
A fish tank and fish bowl are the same temperature. Which has more thermal energy and why?
The fish tank has more thermal energy because there are more items (decorations/fish) in the tank that will generate more thermal energy.
What are the types of kinetic energies?
- thermal energy
- sound energy
- electromagnetic energy
- electrical energy
Deposition is...
when water vapor changes state directly from a gas to a solid
What are two processes in the water cycle that are driven by gravity?
Precipitation and run-off
Engineers are studying each material’s thermal conductivity, or how easily a material can transfer thermal energy in the form of heat. Based on the information below, which material should the engineers use to make cooling sheets?
Material Thermal Conductivity
copper 401
bronze 110
iron 80
tungsten 174
copper
- chemical energy
- nuclear energy
- gravitational potential energy
- elastic potential energy
Law of Conservation of Energy
Energy cannot be created or destroyed
Describe how water moves throughout Earth and the atmosphere. You may use the parts of the water cycle in your answer.
The sun heats up water on Earth. The water starts to evaporate and condenses into clouds. Clouds will become heavy enough, which allows for precipitation. As precipitation occurs, the water falls back down to Earth. Then, the water flows through run-offs, which lead back to the ocean or other bodies of water. Or the water goes through the process of infiltration in which it seeps into the Earth's soil.
Provide an example of how radiation, conduction, and convection work all together in daily life.
Sample answer: boiling water. The heat from the flame is radiation. The heat from the flame then heats up the stove, which is conduction. As the water boils, this is demonstrating convection.
Describe a real life example of when potential and kinetic energies work together in daily life.
Sample answer: Bow and arrow. Pulling back the arrow is potential energy as it is stored energy and has the potential to move. Once the bow is released, the potential energy is converted to kinetic energy as the bow flies.
