____ is transferred between materials through methods such as convection, conduction, and radiation.
Heat
What is particle theory?
All matter is made up of tiny particles that are constantly moving. The speed of the particles depends on the state of matter they are in.
What are the three ways that heat is transferred?
Convection, conduction, radiation
As matter heats up, it will:
a) expand
b) contract
Matter will expand when it heats up
True or False: The relative distance to the equator is the only thing that affects a locations climate and temperature.
The transfer of heat between solids through direct contact.
Conduction
True or False: Only warm things have thermal energy.
False. All matter contains thermal energy.
True or False: Conduction transfers heat between liquid matter through direct contact.
False
True or False: A basketball will be more deflated if it is left in the cold.
True. The air inside contracts making it less inflated.
This type of energy can be replenished easily.
Renewable energy
The transfer of energy through fluids (liquid or gas)
Convection
What is it called when matter from a liquid state heats up and changes to a gaseous state?
Can a heat source transfer heat in more than one way at a time? Give an example.
Yes. For example, a fire place will heat a room by causing warm air to rise and circulate. We can also feel the heat radiating from the fire.
What is the process called that creates heat from the sun?
Nuclear fusion
How are humans increasing Greenhouse gases?
Burning fossil fuels, large scale farming, clear cutting forests etc.
The transfer of energy through waves without needing the movement of particles.
Radiation
Can a solid change state to become a gas? If so, what is it called?
Yes. It is called sublimation
What is it called when hot air rises and then sinks forming a cycle?
Name 4 ways that heat is generated.
The sun, fire, mixing chemicals, electricity, friction
What are some ways that humans can reduce greenhouse gases?
Moving to clean energy such as solar or wind energy, cleaner methods of transportation, less shipping and trade (shopping local) etc.
___ is created when a rise in temperature causes the atoms to move faster and collide with each other
Thermal energy
Particles are vibrating in place and begin to speed up. Give me a real life example that shows the change in state.
Ex. Ice to water
Matter can absorb or reflect this type of heat transfer.
Radiation
True or False: When matter changes state, heat is absorbed or released.
True. If heat is absorbed, the matter becomes warmer. If heat is released, matter becomes colder.
What are greenhouse gases?
Greenhouse gases are trapped by our atmosphere creating a "blanket" around our earth and causing it to heat up.
