heat pt2

Question 1

What is conduction

Answer 1

Heat travelled through a solid using contact from molecules.

Question 2

What is convection

Answer 2

Convection is the process of transferring heat through air or liquid currents. Convection causes liquid or gas to heat up, expand, and decrease in density.

Question 3

what is radiation

Answer 3

Energy is transferred through waves, without needing a medium (solid, liquid, or gas).

Question 4

how do thermometers work?

Answer 4

the heat causes the molecules to move faster meaning they need more room so they rise

Question 5

What is temperature

Answer 5

Temperature is a measure of the average speed/energy at which individual molecules are moving

Question 6

What is heat

Answer 6

the transfer of thermal energy between substances

Question 7

what is the diff from day and night wind currents

Answer 7

At night, there is no surface heating and therefore less turbulence and the surface wind tends to resume its normal direction and speed
