I assume ...
Thermal meaning warm(th) and by upwards flow you would be talking about air? Immagine this ...
If you take a bit of metal and you warm it up (a lot), it expands. something very similar happens to the air. When you warm things up what you are really doing is making the particles move around a whole bunch more ... meaning that they need more space.
Now if the particales are suddenly taking up more space and so are further apart from each other you will have fewer particles in a 10 by 10 space full of warm air than in a 10 by 10 space of cold air. This means that the 10 by 10 space of warm air is also lighter than the 10 by 10 space of cold air and so can rise to the top, creating an 'upward' flow.
If we didnot live on a planet and so did not have such a strong gravitational field, this wouldn't happen! (not to mention that there is no proper 'up and down' in space)
There is no particular difference between heat and thermal energy. Heat is a form of thermal energy. Since thermal energy is energy from heat, heat and thermal energy are basically the same thing.
The suffix for thermal energy is "ies" as in "energies". The word "thermal" is derived from German. Thus the suffix for thermal is "en" as in "thermalen".
Yes. Thermal means heat, so thermal energy is the energy that is produced by heat. Thus, when the heat is added to a system, thermal energy is said to have risen, and if heat is removed, it implies that thermal energy is decreased.
Heat is the transfer of thermal energy.
what is thermal energy converted into work called
heat
yes or no ______________________________________ yes
yes it is
Yes, thermal energy flows from hot to cold.
Thermal energy flows from an object with a higher temperature to one with a lower temperature until thermal equilibrium is reached. This flow can occur through conduction, convection, or radiation, depending on the medium through which the energy is transferring. The rate of heat transfer is dependent on factors such as the temperature difference, the thermal conductivity of the material, and the surface area involved.
yes or no ______________________________________ yes
Energy has many different forms. A few of the most commonly thought of forms are electricity, thermal, and kinetic. Thermal Energy is energy expressed through a changing (usually upwards) in the temperature as heat.
it doesnt i dont think.
because thermal energy always flows from warmer matter to cooler matter
Thermal energy flows from the hotter substance to the colder substance until thermal equilibrium is reached, where both substances reach the same temperature.
The flow of thermal energy is called heat transfer. It is through the various means of heat transfer that thermal energy moves from one place to another. Heat moves from where it is hot to where it is not. Always. Think it through and it will make perfect sense.
Higher temperature to lower temperature. Thermal energy will always flow down the energy gradient.
