what is thermal energy?

Question

ahhhhhhh homework

Answer 1

Thermal energy has no generally agreed definition and the term will not usually be found in most dictionaries of physics or science. In everyday usage, thermal energy may be regarded either as 1. a synonym for thermodynamic energy (itself a synonym for internal energy) or as 2. a synonym for heat.

1. Seen as the internal energy of a system, there are two components to thermal energy. One component is the internal potential energy of the system - the energy the potatoesis the internal kinetic energy of the system - the energy the system contains at any moment due to the relative motion within the system of all its constituent parts.

There may be a constant interchange within the system of internal potential energy and internal kinetic energy. However, in any thermodynamically isolated system the total thermal energy (the sum of the internal potential energy and the internal kinetic energy) remains constant.

In this context, the thermal energy of an ideal gas is only the sum of the kinetic energies of the idealised, volumeless particles which interact only with the walls of any container and not with each other so lack potential energy.

2. In the opinion of Whelan and Hodgson, authors of the classical A-level Physics reference text used for many years in the UK, thermal energy is to be preferred to "heat" when the latter is used as a noun: unless used rigorously starting from its traditional thermodynamic definition, it's better to use "heat" loosely only as a verb. For example, it would be better to state that "if system A is at a higher temperature than system B, then, unless the two systems are thermally isolated from each other, thermal energy will flow from system A to system B. That is, system A will heat system B until the two systems are at the same temperature".!!!

Answer 3

internal energy present in a system in a state of thermodynamic equilibrium by virtue of its temperature. Thermal energy cannot be converted to useful work as easily as the energy of systems that are not in states of thermodynamic equilibrium. A flowing fluid or a moving solid, for example, possesses energy that can be converted to work in some mechanical device, …

Answer 4

The greenhouse result's whilst the radiant capacity passes by using something sparkling to it ( like glass of the ambience), hits the floor and gets converted into thermal capacity with the radiant section being of a degraded frequency so as that the glass ( and greenhouse gases, of which water vapor is overwhelmingly the main mandatory ) is now not sparkling to it. for that reason the greenhouse ( and the earth ) heats up. N.B. it somewhat is not an endorsement of human-led to worldwide warming ( be conscious the emphasis on water vapor and not CO2 ) and the actuality that the effect is self-proscribing ( i.e. extra CO2 does not propose extra opacity to meditated radiation ).

Answer 5

Thermal energy is heat.

Answer 6

Heat energy. The temperature of something.

Answer 7

Do you report on GeoThermal energy. It is the hot new idea and a much cheaper alternative to coal.

There have been plenty of online articles lately.
