thermometers
a device used to measure temperature
particle model of matter
The idea that everything is made up of small parts that you cannot see.
energy
Often referred to as the ability to do work.
Celsius
The most common scale for measuring temperature.
thermal energy
The total kinetic energy of a substance, due to movement of the particles.
Temperature
How hot something is. A measure of how fast the particles are moving
Kelvin scale
A scale for measuring temperature in scientific experiments. None of it's values are negative.
Melting
It does not start with a "F". This is a change of states from solid to liquid.
Freezing
means the same thing as solidification. This is a change of states of matter.
condensation
The change of state from a gas to a liquid.
solidification
changing from the state of a liquid to a solid. This is the same as freezing.
Sublimation
The changing from a solid to a gas or a gas to a solid. It can be either change of state.
boiling
This is the change of state from a liquid to a gas. It does not start with an "E"
evaporation
This is the change of state from a liquid to a gas. It does not start with a "B"
fusion
means the same thing as melting. This is a change of states from solid to liquid.
radiation
The transfer of energy. It travels in the form of an electomagnetic wave.
thermal conduction
The movement of thermal energy or heat from one particle or object to another through collisions.
heat insulators
Stuff that slow the transfer of thermal energy or heat from one object to another.
Fluids
A type of matter that takes the shape of its container, lacks a definite shape and can flow.
convection current
The circular movement from the rising of warm materials and the sinking of cooler materials.
geothermal energy
Energy generated in the interior of Earth
cogeneration
energy conservation where waste heat from one industry is used by another industry
Fahrenheit
A scale for measuring temperature in the United States and a few other countries
Expand
the expanding of matter due to particles moving farther apart when heated
Contract
the shrinking of matter due to particles moving closer together when cooling
Geothermal Energy
Energy from the interior of the Earth, using it's heat to create energy
Passive Solar Heating
Using materials to absorb and store solar energy
Active Solar Heating
Using mechanical devices to collect and distribute thermal energy.
