Heat
Definition of heat
The definiton is the energy of moving atoms
Conduction
Convection
Radiation
What is particle theory?
Particle theory describes how the atoms in matter behave and what they do.
What is the strongest shape for a bridge?
The triangle
If the molecules are fast or slower, what happens?
When molecules are faster, they are hotter, and when the molecules are slower, they are cooler
Which type of heat transfer occurs with space and heat waves?
Radiation
Name at least two parts of particle theory (does not have to be in order).
Why can't heat be transferred?
Heat is a form of energy, so it can't be transferred
Name at least 2 examples that have all three types of heat transfer.
Boiling water and a washing machine.
Particle theory to explain thermal expansion
Heating up a substance so the molecules heat up and get excited, causing them to move faster and expand.
What does the red number in the corner represent?
Protons, electrons, and the atomic number
What is the cold conspiracy?
"Cold" isn't a thing - it is just the absence of heat
True or false: A dryer only has two types of heat transfer?
False. It has three types of heat transfer
What are particles doing in solids, liquids, and gases?
Solids, they are vibrating in place
Liquids and gases move freely past each other
5 different types of bridges
Beam, suspension, cantilever, cable, arch
How does a thermometer work
Thermometers work by measuring a predictable physical change in a material that reacts consistently to heating or cooling
From greatest to least, which heat transfer has the most kinetic energy?
Conveciton
conduction
radiation
What are the five steps of particle theory in order?
1. All matter, solids, liquids and gases, are made up of tiny particles. No matter how broken down they are they always act like the matter they are.
2. All matter has spaces between them.
3. All matter is constantly moving.
4. The same kind are connected by bonds.
5. Faster when heated, slower when cooled.
