Temperature is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion. ... The terms hot and cold are not very scientific terms.
Explanation:
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.
Answer:
Explanation:
One has to be careful when defining temperature not to confuse it with heat. Heat is a form of energy. Temperature is something different. We could begin with a technical definition, but I would prefer to start with a question. How hot is it? The answer to this question (or a question like this) is a measurement of temperature. The hotter something is, the higher its temperature. Therefore I would like to propose the following informal definition — temperature is a measure of hotness.
Quantities in science are typically defined operationally (through the process by which they are measured) or theoretically (in terms of the theories of a specific discipline). We will begin with a theoretical definition of temperature and end with an operational definition.
