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? 0°c 37°c 0°c 37°c 37°c 0°c 37°c 0°c

Explanation:

Step1: Recall heat - flow principle

Heat flows from a region of higher temperature to a region of lower temperature.

Step2: Identify temperatures

The ice cube is at \(0^{\circ}C\) and Juan's hand is at \(37^{\circ}C\). Since \(37^{\circ}C>0^{\circ}C\), heat will flow from Juan's hand (at \(37^{\circ}C\)) to the ice cube (at \(0^{\circ}C\)).

Answer:

The diagram with \(37^{\circ}C\) on the left (Juan's hand) and \(0^{\circ}C\) on the right (ice cube) and an arrow pointing from the \(37^{\circ}C\) circle to the \(0^{\circ}C\) circle.
