What does Solar Collectors mean?
Mechanical systems and devices, usually contaning water, or air, used in active solar heating.
What is a thermometer?
A thermometer is a device that measures temperature.
Solid- Ice block
Liquid- water
Gas- Air
Name 3 ways of transferring thermal energy.
Convection, Conduction, Radiation.
What is geothermal
Energy harness from the earth.
What is the Celsius Scale
The most common scale
Name 4 of the most important ideas of the model.
All substances are made out of small particles that we cant see with the naked eye. The particles are always in motion, vibrating, rotating, and moving to place. The particles have spaces between them. As temperature increases/decreases the motion goes faster/slower
What are Heat Capacity and Specific Heat capacity?
Heat capacity- The amount of thermal energy that warms or cools by one degree Celsius
Specific Heat Capacity- the amount of thermal energy that heats or cools, one gram of a material by one degree Celsius.
Name the 5 features of all energy transfer systems. Define them as well.
Energy Source- Some part of the system that acts as an energy source.
Direction of Energy Transfer- Energy transferred away from concentrated sources.
Transformations- Energy transferred from one place to another place.
Waste heat-Energy that can transfer at least a little transfer energy into the surroundings.
Control systems- Systems that control the energy transfer.
Name 2 examples for converting Mechanical forces to thermal energy.
1. Mechanical forces that push or pull objects that release energy. Car brakes, bicycle brakes.
What is energy?
Is a measure of something's ability to do work
What's the difference between temperature and thermal energy
The average kinetic energy is called temperature. The total kinetic energy is called thermal energy.
What is Hidden Heat
The energy that is hidden from temperature.
Name 3 different forms of EMR.
Radio waves, microwaves, and visible light.
Name 2 problems with fossil fuels.
Been using it for a long period of time and only have half of it left. Also, fossil fuels are non-renewable which means it takes very long for them to be created.
What are Expansion and contraction?
Expansion- Incrases in volume
Contraction- Decrease in volume
What does the thermocouple, Recording Thermometer, measure?
Thermocouple- It measures very hot temperatures. Recording thermometer- It records the temperature during a long period of time.
Does light take up space or have. True or false
True
When is carbon monoxide produced? How is it dangerous?
When fire burns without enough oxygen. It's dangerous because it can make you dizzy and there isn't any smell or taste.
What is global warming and why is it bad?
Global warming is heating up the earth and it increases the amount of thermal energy and breaks our enivorment
What is Evaporative cooling? Give me 2 examples of how Evaporative cooling is useful.
A process in which the fast-moving particles on the surface of the liquid evaporate and escape into the air; the slower-moving particles, which are left behind and have lower kinetic energy, decrease the temperature of the remaining liquid and the surface on which it is remaining. Ex. Joggers feel cold as their clothes dry out after getting soaked in a rainstorm. A Homeowner sprays the roof of a house with water to cool the house down on a hot summer day.
What is an advantage and disadvantage of using a thermocouple instead of a thermometer?
The thermocouple measures a very high temperature than a regular thermometer. A disadvantage is they cant measure very low temperature
What are an Astrophysicists?
Someone who studies the way stars work.
Where should place the fire detectors be placed?
Places where fire can be created easily. For ex Kitchen.

4. Water
5. Air
6. Soil
7. Cultivated Plants
8. Biomass
9. Biofuels
