Particle Theory & Heat
When heat is added to a liquid, its particles do this faster.
What is moving?
Heat transfer through direct contact between particles.
What is conduction?
This is a common way heat is generated when two objects rub together.
What is friction?
These gases trap heat in Earth's atmosphere.
What are greenhouse gases?
Coal and oil are examples of this type of energy source.
What are non-renewable energy sources?
This theory explains how particles move and change when heated or cooled.
What is the Particle Theory of Matter?
Heat transfer that happens through movement of fluids like air or water.
What is convection?
Dark, dull surfaces absorb more of this from the Sun.
What is radiation?
The main role of greenhouse gases in Earth’s atmosphere.
What is trapping radiated heat and warming the planet?
Wind and solar are examples of this cleaner energy type.
What are renewable energy sources?
Heating a solid usually causes this change in volume.
What is expansion?
Heat transfer that does not need particles and can travel through space.
What is radiation?
Insulation in a house is used mainly to do this.
What is reduce heat loss?
Burning coal, oil, and gas releases large amounts of this.
What are greenhouse gases (or carbon dioxide)?
One environmental benefit of renewable energy.
What is reducing greenhouse gas emissions?
A balloon expands in a hot room because the particles inside do this.
What is moving faster and spreading further apart?
This method of heat transfer mainly occurs in liquids and gases.
What is convection?
Using insulation reduces the need for this in winter.
What is heating energy?
One major impact of climate change caused by energy use.
What are changing weather patterns or melting ice caps?
One social benefit of using renewable energy.
What is cleaner air or improved public health?
This state of matter has particles that move freely and expand easily when heated.
What is gas?
The Sun warming Earth is an example of this type of heat transfer.
What is radiation?
A natural process that depends on convection in Earth’s atmosphere.
What is wind formation (or air circulation)?
This effect helps keep Earth warm enough for life but can cause warming when increased.
What is the greenhouse effect?
A way humans can reduce greenhouse gas emissions at home or school.
What is using less energy, renewable energy, or increasing insulation?
