Heat And Temp. Unit Test Review

Front 1

name two things on geo thermal energy.

Back 1

It is related to the thermal energy
It is pretty much an unlimited source of energy

Front 2

All heating systems must have a source of ______ in order to produce heat

Back 2

thermal energy

Front 3

what is thermal energy?

Back 3

thermal energy is the total kinetic energy of the particales in a substance

Front 4

what is the freezing point for C, F, and Kelvin?

Back 4

C - 0
F - 32
K - 273.15

Front 5

what is the boiling point for C, F, and Kelvin?

Back 5

C - 100
F - 212
K - 373.15

Front 6

what is a conductor? insulator?

Back 6

conductor - material that allows heat energy or electricity to flow easily
Insulator - material that does not allow heat energy or electricity to flow easily

Front 7

what is kinetic energy?

Back 7

it is the energy of movement; particales that make up matter have kinetic energy

Front 8

what is solar heating?

Back 8

this is when you have windows and you use the sun to heat a room or area

Front 9

is heat a form of energy?

Back 9

yes

Front 10

what are some natural sorces of energy?

Back 10

fire, sun, geothermal, decaying matter

Front 11

examples of geothermal

Back 11

hot springs, volcanoes, etc..

Front 12

a little on insulators

Back 12

Every insulator is given an R-value (aka RSI value); the higher the R-value the better it is at providing insulation

Front 13

what is thermal conductivity

Back 13

the ability to transfer heat by conduction

Front 14

All substance are made up of tiny _____

Back 14

particals

Front 15

Good ______ do not allow heat to move easily through them

Back 15

insulators

Front 16

some notes on tide thermal energy

Back 16

It creates a low liquid or solid pollution
It is renewable source of energy
Environmentally friendly

Front 17

some notes on wind

Back 17

Used to provide electricity
We have been using wind power for at least 5000 years

Front 18

notes on nucular energy

Back 18

There are 104 nuclear power plants in America
It produces electricity, water, etc...

Front 19

notes on fossil fules

Back 19

You don’t need trees to use it
Made up of natural substance
Many people rely on fossil fuels for electricity, water, etc...

Front 20

how does a thermostat work?

Back 20

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.

Front 21

what are the three different ways to measure temp. and who invented them?

Back 21

Celcius -Anders Celsius
Fahrenheit - Daniel Gabriel Fahrenheit
Kelvin - Lord William Thomson Kelvin

Front 22

what do the particals look like in a solid, liquid, and gas?

Back 22

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

Front 23

what is it called when a liquid changes into a gas?

Back 23

evaporation

Front 24

What is it called when gas turns into a liquid?

Back 24

condinsation

Front 25

What is it called when a solid turns directly into a gas?

Back 25

sublimation

Front 26

What is it called when a gas turns into a solid?

Back 26

Deposition
