Muliple heat sources, same object - final temperature reasoning
2017年5月25日 · What happens when two or more independent heat sources heat the same object? For example, where one heat source on its own creates an equilibrium temperature with the object of 35C, and the other creates an equilibrium temperature with the object at 50C - …
Modelling multiple heat sources? - Physics Stack Exchange
Such as, taking a server and modelling the temperature decrease over time and models taking distance into account based Fourier's equations. However I am now looking to step the model into 2 dimensions and this involves considering a stack of servers with multiple heat sources stacked on each other (such as a server rack).
What is a heat source and heat sink in relation to thermodynamics ...
2014年12月9日 · As mentioned above, but important to stress, the temperature of the reservoir does not change when heat is added or extracted because of the infinite heat capacity. As it can act as a source and sink of heat, it is often also referred to as a heat reservoir or heat bath. And in the context of a thermodynamic cycle, a heat source and a heat sink.
A paradox involving heat exchange between two heat sources
2018年7月29日 · The same goes for connecting two heat sources. All real heat sources have finite capacities, their surfaces are not ideal, the emissivity is not constant, the temperature changes during connection and it is not uniform throughout, etc. If you ignore these when directly connecting them you get contradictions in your calculation when in fact your ...
To what extent do (man made) generators of heat from internal …
2019年2月8日 · Similar thing is true for many (probably most) industrial use of electric energy - most of it dissipates into heat in the atmosphere, ocean and Earth crust. This too contributes to heating the planet. (Part of this energy - from renewable sources - would heat the planet anyway, but in 2019 that is a small percentage of total energy consumed.)
Pluto's internal heat source - Physics Stack Exchange
Radioactivity. Best supported, as pointed out by Emilio Pisanty, on §2.2 of Icarus 216, 426 (2011) ().. First, Pluto having an internal source of heat is indeed the most likely scenario (if Pluto and Charon are as old as expected), not only given its apparent youth, but also due to the absence of compressional features on its surface, according to recent paper,
How does Infrared Relate to heat? - Physics Stack Exchange
2013年10月16日 · There is no special link between heat and infrared radiation, except for the fact that most bodies radiate most of their heat in the infrared spectrum because they don't have enough energy (heat) to radiate at a higher frequency. See the graphs in this thread. So one could claim the same connection between X-rays and heat.
If two objects of different temperatures have the same heat source ...
2018年7月13日 · Applying a heat source raises the temperature of A by 10 degrees up to 110 degrees. With no modifications, the heat source is applied to B. Again, all other things being equal: should B be expected to heat up by 10 degrees also, or by some other amount? For an example, consider a room that you want to warm with a fire.
thermodynamics - What's the temperature distribution of a plane …
Over here, you have a hot liquid on one side, but it is not necessary that a hot liquid gives out heat continuously. It will give out heat till the wall attains the same temperature, after which there will be no net flow of heat. Over here I am assuming that the top and bottom of the wall are insulated (based on the 'no sources/sinks of heat'.
Is heat always associated with Light? - Physics Stack Exchange
2015年8月19日 · $\begingroup$ Light does not produce heat. It is the absorption of light that produces heat. Light is energy. Heat is energy. When a physical body absorbs light, it converts the energy of the absorbed photons into kinetic energy (vibrations) of its own atoms. We call that mechanical energy "heat". $\endgroup$ –
