Heat 1
The intensity or strength of heat in a substance thing
Temperature
Parts of matter
Particles
Particles are close together, not moving around, vibrating in place
Solid
Solid → Liquid
Melting/Fusion
Particles move closer together, decreasing the volume
Contract
Chemicals from plants and other organisms that died and decomposed millions of years ago and have been preserved deep underground.
Fossil Fuels
Energy is taken by the substance
Absorb
Materials or substances that poorly conduct heat
Insulators
Accidental warming of the environment
Thermal Pollution
Liquid → Solid
Freezing/Solidification
Form of electromagnetic radiation beyond visible light. Cameras can detect heat using infrared thermograms
Infrared
A temperature scale based on human body temperature as a reference point
Fahrenheit Scale
Liquids that evaporate easily at low temperatures, used in fridges and air conditioners
Refrigerants
Sources of energy that can be replenished as quickly as it is used by humans
Non-Renewable Energy
A temperature scale based on the melting and freezing points of water as a reference point
Celsius Scale
A temperature scale based on absolute zero as a reference point
Kelvin Scale
Heat (thermal energy) spreads from one particle to the next, warming up a material as each particle warms
Conduction
Solid → Gas
Sublimation
Thermal energy that comes from the heat of the Earth
Geothermal Energy
A way of warming a house by using solar collectors to collect heat, convert it and transfer it around the house in different forms
Active Solar Heating
Gas → Solid
Deposition
Made of two different metals joined firmly together. As the strip is heated, one metal expands more than the other.
Bimetallic Strip
A theory that explains how the particles that make up a substance are arranged, and how they move and interact with each other
Particle Model of Matter
A way of warming a house by using certain materials that trap and insulate heat in the house, storing the energy
Passive Solar Heating
Uses this waste heat to generate electricity or heat buildings, or do other useful tasks
Cogeneration
