Question

the particles of an ice cube at 0°c (represented by the blue circles) come in contact with the particles of juans hand at 37°c (represented by the orange circles). which diagram correctly represents the temperature of the two substances and the direction of heat flow?

Explanation:

Step1: Understand heat - flow principle

Heat always flows from a higher - temperature object to a lower - temperature object.

Step2: Identify temperatures

The hand is at 37°C and the ice cube is at 0°C. So heat will flow from the hand to the ice cube.

Answer:

The diagram with 37°C on the hand side (orange circle) and 0°C on the ice - cube side (blue circle) and an arrow pointing from the orange circle to the blue circle.
