#### Storyboard Text

• What is thermal equilibrium?
• Thermal equilibrium occurs because heat loss is equal to heat gain.
• So when 2 objects that are at different temperatures ﻿
• I think I got it! Thanks for the help!
• Thermal energy travels the best through solids because the particles are close together. When heat meets another object, the particles move and go another, and that's how the heat travels.﻿
• And conductors like metal allow thermal energy to travel faster than an insulator material like plastic.﻿
• How do we know the rate of how fast thermal energy transfers?
• The mathematical equation for rate of thermal energy transfer is Rate = k•A•(T1 - T2)/d﻿
• Well, first we look at different variables like materials that it travels through. There's also area and distance.﻿
•  If the thickness of the material through which heat is transferred is increased by a factor of 2, then the rate of heat transfer is decreased by a factor of 2
• Exactly!﻿
• So if the thickness of a material increases, the rate of heat transfer decreases!﻿
