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.

2014年12月22日 · The heat radiates away from the source equally in every direction (until it hits something). Imagine the sun. It is roughly spherical and radiates energy (some as heat) in all directions. The energy is radiated in a sphere. As the energy travels away from the source (the sun) the sphere expands but the amount of energy remains the same.

2024年8月4日 · You can make something hotter than the source using an active system, such as one which generates electricity and uses that for heating, but it is important to note that such a generator will need a temperature differential to work with, a cold 'rest of the world' into which waste heat is transferred (and there will necessarily be some waste heat)

2016年9月26日 · But of course you $\textit{can}$ increase temperature of (finite) heat source by means of heat $\textit{pump}$, which is a reversed heat engine that takes some external work input. Response to edit: Whether heat source's temperature would be greater in case B than case A, depends on specifics of the heat engine employed.

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,

2017年9月20日 · Distance from heat source; Heat of heat source; Heat being given off by metal; Heat being asorbed by metal; Volume of metal; Heat capacity of metal(not shown) Other notes :-I think I have to know 2 and 1 before I can know 4. And I have to know 5 and 6 before I …

2018年7月13日 · - IE: your heat source does not cool or run out of fuel until object A reaches 110 degrees, at which point the heat source is removed from the equation and object A continues to heat or commences cooling to match the surrounding temperature. Object B starts at 200 degrees. You apply a temperature of 110 degrees to B.

2019年1月26日 · Heat equation volume source vs. heat flux boundary condition. Ask Question Asked 5 years, 11 months ago.

2021年4月10日 · But as per the image attached below this shows that Q1∞373K(temperature of the heat source) and Q2∞293K(temperature of the heat sink). So my question is when the cylinder comes in contact with the heat source is it let to …

2023年9月7日 · $\begingroup$ "at which time I imagine the source would need to provide an infinite amount of power to stay at constant temperature": Hint: in a medium of finite density, what is the mass of a region of infinitesimal volume? How much energy is required to increase the temperature of such a mass by 1 degree?
