Question

A colored thermal image shows a yellow person sitting in front of a red and orange computer screen. The rest of the room is blue. A scale runs from 20.3 degrees Celsius at blue through green and yellow to orange and red at 40.3 degrees Celsius.

This thermogram shows a person using a computer. Complete the sentence to describe the flow of thermal energy between the person and the computer.

Answer 1

Thermal energy flows from warmer to cooler objects. In the given thermogram with a yellow person and a red and orange computer screen in a blue room, thermal energy will flow from the person to the computer screen.

Step-by-step explanation:

The thermal energy will flow from the warmer object to the colder object, so in the thermogram you described, where a yellow person (indicating a warmer temperature) is sitting in front of a red and orange (also warm but likely not as warm as the person) computer screen, and the rest of the room is blue (cold), thermal energy will flow from the person to the computer screen and then to the surrounding cooler environment.

This is because heat moves from regions of higher temperature to regions of lower temperature until equilibrium is reached as demonstrated by the infrared thermographs. Hence, the correct completion of the sentence to describe the flow of thermal energy between the person and the computer would be: Thermal energy will flow from the person to the computer screen.
