Sources of Heat Technology
Chemicals from organisms that decomposed millions of years ago and have been preserved underground in the form of coal, oil, and natural gas.
This technology is used to control the air temperature of indoor environments.
What is... a Thermostat
The process by which a solid turns into a gas.
What is... Sublimation.
The measure of how hot or cold something is, indicated by the average speed of the particles in motion in a substance.
What is... Temperature.
The process of transferring thermal energy from the direct collisions of particles.
The type of energy created when the sun heats the air, causing warm air to rise and cool off creating convection currents called thermals.
It is composed of two different metals fused together into a coil and when heat is applied to the end, one of the metals will expand faster than the other and operate a switch.
What is... a Bimetallic Strip
The name given to materials that do not easily allow heat transfer.
Energy from the interior of the Earth.
Type of heating system that heats the whole house.
What is... Central Heating.
Why does an ice cube melt into water?
Heat Energy has been added.
Move very fast.
Not attracted or bonded.
Very far apart from each other.
The transfer of thermal energy in fluids, by the circular motion of the particles.
The energy produced from the fission of radioactive uranium to produce vast amounts of heat.
What is... Nuclear Energy
The use of materials in a structure to absorb, store, and release the solar energy.
Power generated from dams that use gravitational force to direct water from a reservoir through gates in the dam to turn turbines attached to generators.
When an object starts to cool down, what happens to the size of the object?
The transfer of energy without any movement of matter.
