Question

multiple choice question
how do humans judge temperature without the use of instruments such as thermometers? choose the most common process.
o by seeing the frequency of infrared waves emitted by an object
o by using the color of objects
o by sensing the flow of energy either into or away from their bodies

Explanation:

Humans cannot see infrared waves or use object color to judge temperature without instruments. However, they can sense heat transfer (energy flow) to or from their bodies. For example, when touching a hot object, heat (energy) flows into the body (sensed as hot), and when touching a cold object, heat flows out of the body (sensed as cold).

Answer:

By sensing the flow of energy either into or away from their bodies
