in waves
What is earths largest producer of Heat
The Sun
The process by which a solid becomes a liquid is called what
Melting
What is a conductor
A material that allows heat to pass through it easily
The freezing point of water is 0oC, what other phase change point is also 0oC
Melting Point
The 3 ways that heat travels are what
Conduction, Convection, Radiation
What are the 3 ways to produce heat
At what temperature does what begin to evaporate (in Celsius)
100oC
What type of material is often the best Conductor
Metal
A phase in which gas changes directly to a solid
Deposition
Transfer of heat through direct contact
Conduction
through what type of method does a microwave produce heat
Radiation
the process by which a gas becomes a liquid is what
Condensation
Which of the following is an insulator
Copper, Air, Wood, Aluminum
The total amount of energy from all moving particles in a substance
Thermal Energy
During convection heat travels through fluids. What is a fluid
liquid or gas
Explain how both conduction and convection are used to make pasta
Convection boils the water through density changes and then conduction cooks and softens the pasta from direct contact between pasta and boiling water
Give an example of sublimation
dry ice
Explain how a foam cooler works to keep drinks cold
the foam slows down the heat from outside when it tries to get into the inside of the cooler
