16
Q

The movement caused within a fluid (currents) when hotter less dense material rises and colder denser material sinks.

A

Convection

17
Q

The emission of energy as electromagnetic waves move

18
Q

A substance or material that allows electricity and heat to flow through it

19
Q

A substance that does not readily allow the passage of heat or sound.

20
Q

the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.

21
Q

What is the equation for KE? What is the equation for gravitational potential energy?

A

KE=1/2 m(velocity squared)
Label is Joules
GPE=mgh Label Joules

22
Q

What is the law of conservation of energy?

A

Energy is neither created nor destroyed only transfered

23
Q

Explain why we use copper and iron cooking pans. Relate your answer to heat transfer and to specific heat.

A

They are good heat conductors and they have a low specific heat so they heat up faster

24
Q

What is the freezing and boiling point for the 3 temp scales?

A

F 32 212 C 0 100 K 273 373

25
Give and example of a good insulator and a good conductor.
Conductor copper insulator rubber wood plastic
26
List 2 scenarios when thermal energy transfer, or thermal insulation, is inhibited.
Shivering to keep your body warm Insulation in a house Putting on layers to keep you warm
27
Give a real-world example of heat transfer.
Stove to the pot, the stove's heat is transferred into the room temp pot and this gets hot fast due to the extreme temp difference
28
Give an example of all 3 types of heat transfer.
Conduction stove to pot Convection air popper and radiation microwave
