Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter. Temperature is measured with a thermometer.

Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).

Answer 2

We used to judge temperature based on human perception - whether an object was hot or cool was largely judged by human touch before the formation of the idea of temperature.

Explanation:

• Temperature is a term that describes the physical qualities of matter and quantifies the hotness or coldness of a body.
• Many people mistake temperature for energy, which is not the case. Temperature is just a measurement of one atom's or molecule's average kinetic energy.
• As a result, we often use another reference point to define the hotness and coldness of a body when we say something is hot or cold. When we state that the coffee is hotter than the ice cream, we're referring to the ice cream as a temperature reference point for the coffee.
• Temperature and humidity are displayed in two columns during weather reports. Because of human perception rather than temperature changes, hot and humid days are perceived as hotter than hot and dry days. If the temperature is the same but the humidity is high, a person may feel hotter because sweat does not drain as quickly on humid days as it does on dry days.
