Question

1. deep ocean water 17. boiling cooking oil

for each example, draw arrows to represent the movement of thermal energy from one substance
to another.
movement of thermal energy

1. an open refrigerator 19. hot coffee 20. a glass of ice water

outside to inside of refrigerator
inside to outside of refrigerator
have reached thermal equilibrium on the table below.
ples of thermal equilibrium

Explanation:

Step1: Analyze thermal energy movement for open refrigerator

Thermal energy moves from higher - temperature area to lower - temperature area. The inside of an open refrigerator is cooler than the outside. So, thermal energy moves from outside to inside of the refrigerator.

Step2: Analyze thermal energy movement for hot coffee

Hot coffee is at a higher temperature than the surrounding air. So, thermal energy moves from coffee to air.

Step3: Analyze thermal energy movement for a glass of ice water

The ice water is at a lower temperature than the surrounding air (assuming room - temperature air). So, thermal energy moves from air to ice water.

Answer:

1. outside to inside of refrigerator; 19. coffee to air; 20. air to ice water
