Describe a rule for how thermal energy moves from one location to another, regardless of if it is conduction, convection, or radiation.

The temperature difference is the driving force for heat transfer.

The larger the temperature difference, the higher the heat transfer rate. Therefore the temperature difference is responsible for the existence of thermal energy exchange processes.

Explanation:

Experience tells us that if you leave a cold can of drink on the table, at some point it will reach the room temperature, while  that a hot baked potato will cool down. When a body is placed in a  medium that is at a different temperature, Energy Transfer has  place between body and medium until thermal equilibrium is established,  It means, when they both reach the same temperature. The direction of the  Energy Transfer is always from the body with a higher temperature to the one with the lower temperature.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
