Heat Transfer
What is the process by which heat moves through a solid material?
Conduction
This is the change from a liquid to a gas.
Evaporation
a measurement of how hot or cold an object is
Thermometer
An increase in the volume of a substance caused by heating
thermal expansion
a combination of several types of energy from the Sun, including visible light, ultraviolet radiation, and infrared radiation
Solar energy
What type of heat transfer occurs when warm air rises and cool air sinks, creating a current
convection
The change from a gas to a liquid, like when steam cools down and forms water droplets on a cold surface.
Condensation
This is the transfer of energy from warmer matter to cooler matter
Heat
The process by which a metal expands when it is heated is why this happens to the rails on a train track in the summer.
Thermal expansion
Is a material that does not allow electricity or heat to pass through it easily. These are used to prevent the flow of electric current or to stop heat from escaping or entering.
Insulator
What is the name of the heat transfer method that does not require a medium, like space or a vacuum?
radiation
This is the process of changing from a solid directly to a gas, skipping the liquid phase.
Sublimation
A pot of soup cooking on a stove is an example of
convection
Frost is an example of this change of state going directly from gas (water vapour) to a solid.
Deposition
Double pained windows, sealing cracks, and fixing drafts around your house will help you.
Prevent Heat loss
Name one type of material is a good conductor of heat?
Metal
When water freezes and turns from liquid to solid, this is called
Freezing
A form of convection, carries warm water from the Gulf of Mexico to northwestern Europe.
The Gulf Stream
This is a decrease in the volume of a substance caused by cooling
thermal contraction
Running in a race on a hot day, you are encouraged to wear a white tshirt by your teacher. Why is this?
White will reflect the suns rays while black will absorb it.
What is the energy a moving object has due to its motion
kinetic energy
This happens when matter changes from a solid directly to a gas.
Sublimation
This is a measure of the average kinetic energy of particles.
Temperature
When you place a metal lid in hot water, it is easier to open because the metal lid has done this.
It has expanded
energy that travels in the form of electromagnetic waves through empty space; includes visible light, ultraviolet rays, and infrared rays
radiant energy
