name two things on geo thermal energy.
|
It is related to the thermal energy
It is pretty much an unlimited source of energy |
|
All heating systems must have a source of ______ in order to produce heat
|
thermal energy
|
|
what is thermal energy?
|
thermal energy is the total kinetic energy of the particales in a substance
|
|
what is the freezing point for C, F, and Kelvin?
|
C - 0
F - 32 K - 273.15 |
|
what is the boiling point for C, F, and Kelvin?
|
C - 100
F - 212 K - 373.15 |
|
what is a conductor? insulator?
|
conductor - material that allows heat energy or electricity to flow easily
Insulator - material that does not allow heat energy or electricity to flow easily |
|
what is kinetic energy?
|
it is the energy of movement; particales that make up matter have kinetic energy
|
|
what is solar heating?
|
this is when you have windows and you use the sun to heat a room or area
|
|
is heat a form of energy?
|
yes
|
|
what are some natural sorces of energy?
|
fire, sun, geothermal, decaying matter
|
|
examples of geothermal
|
hot springs, volcanoes, etc..
|
|
a little on insulators
|
Every insulator is given an R-value (aka RSI value); the higher the R-value the better it is at providing insulation
|
|
what is thermal conductivity
|
the ability to transfer heat by conduction
|
|
All substance are made up of tiny _____
|
particals
|
|
Good ______ do not allow heat to move easily through them
|
insulators
|
|
some notes on tide thermal energy
|
It creates a low liquid or solid pollution
It is renewable source of energy Environmentally friendly |
|
some notes on wind
|
Used to provide electricity
We have been using wind power for at least 5000 years |
|
notes on nucular energy
|
There are 104 nuclear power plants in America
It produces electricity, water, etc... |
|
notes on fossil fules
|
You don’t need trees to use it
Made up of natural substance Many people rely on fossil fuels for electricity, water, etc... |
|
how does a thermostat work?
|
inside of a thermostat there is two billamatic strips of metal and when heated one expands faster than the other thus causing them to bend. this will heat up the room or what ever that it needs to, getting hotter as you add more heat to the metals.
|
|
what are the three different ways to measure temp. and who invented them?
|
Celcius -Anders Celsius
Fahrenheit - Daniel Gabriel Fahrenheit Kelvin - Lord William Thomson Kelvin |
|
what do the particals look like in a solid, liquid, and gas?
|
solid - the particals are close toghether and don't really move around
liquid - vibrate a little and can slide past eachother gas - the particals have a lot more room and move faster than a liquid or a gas |
|
what is it called when a liquid changes into a gas?
|
evaporation
|
|
What is it called when gas turns into a liquid?
|
condinsation
|
|
What is it called when a solid turns directly into a gas?
|
sublimation
|
|
What is it called when a gas turns into a solid?
|
Deposition
|
