Unit 2 Science/Vocabulary Quiz Flashcards
The property of a material that determines how well it conducts/transmits heat. (Examples: Metal generally has a high thermal conductivity, and plastic typically has a low thermal conductivity.)
thermal conductivity
A resource that is not replaceable after it has been used. (Examples: Fossil fuels such as oil or natural gas, iron ore.)
nonrenewable resource
Heat flow due to the contact of two objects or within a solid object.
conduction
The amount of solar radiation that reaches a given area.
insolation/solar radiation
Heat flow due to fluid movement such as water or air.
convection
How much electromagnetic energy is reflected and how much is absorbed by an object in the form of heat. Emissivity is very dependent on color. (Examples: Aluminum foil has a low emissivity because it reflects a majority of heat and a black surface has a high emissivity because it absorbs a lot of heat; a black shirt gets hotter than a white one in the sun.)
emissivity
Energy transferred through the movement of electromagnetic waves; heat transfer not requiring a medium.
radiation
A material that does not conduct heat very well and has a low thermal conductivity. (Examples: A good jacket, fiberglass insulation, a sleeping bag, anything with air trapped in it.)
insulator/insulation
resource that is inexhaustible or replaceable by new growth; limitless supply. (Example: Solar energy.)
renewable resource
