Sentences with phrase «constant internal temperature»

Not exact matches

By accounting for up to the fourth order elastic constants and their temperature dependence, we obtain the temperature variation of the structural parameters of rhombohedral GeTe (the lattice constant, the angle between the primitive lattice vectors and the internal atomic displacement) in good agreement with experiment [1].

The works on display are: 432Hz (2009 - 2014), a wooden shell that contains honeycombs; Vorkuta (2003), a refrigeration chamber where the temperature of -30 °C contrasts with a chair maintained at a constant +37 °C by an internal thermostat; Mindfall (2004 - 2007), a container which contains a chair and tables, on which 21 electric motors turn on intermittently, one after the other, creating a sort of musical composition; Untitled (2003), a small iron room crossed by blasts of hot and cold air channelled into the space by powerful fans; and Sub (2014), a new work specially created for the exhibition at HangarBicocca, an assembly of aluminium and glass display units which the artist originally designed to exhibit her Inner Disorder (1999 - 2001) series of drawings.

As you say «Simples» Think of the ocean as an open pot of warm water with constant heat input (TSI) at a level where water is held at constant temperature by evaporation and internal convection.

So one possible answer of the system is to increase it's internal energy (temperature) and to radiate less what is very logical because Rr being constant, a bit more of it will be consumed to populate the new high energy states so less energy will be available for Re.

Here how it works: Think of the ocean as an open pot of warm water with constant heat input (TSI) at a level where water is held at constant temperature by evaporation and internal convection.

Assume the Earth is devoid of water, the Earth has an internal energy source providing energy at a constant rate, and the Earth's surface temperature without any atmosphere is everywhere T.

So if one uses the heat engine to do external work, the gas in the cylinder will indeed drop to zero in temperature as all of its internal energy drops to the bottom to maintain a constant temperature difference right up to where the temperature of the ideal gas at the top reaches zero.

A polytropic process proceeds with an apparent constant heat capacity Ch and d' Q = Ch dT = Cp dT — R T dP / P When going from T0 to T the changes of the internal energy and of the enthalpy are Cv (T - T0) and Cp (T - T0) while the heat transferred to the gas is Ch (T - T0); it is zero for an adiabatic and RT ln (P / P0) for a constant temperature process.

Internal conditions change, orbital forcing roughly constant during (relatively brief) duration of YD, global average temperature barely changes despite major albedo increase, YD ends, deglaciation continues apace...

Well over half a hectare of Sedum and local grasses it will act as an insulator and keep the internal temperature of the building constant, while providing some habitat and reducing visual pollution.

I believe that if in the vacuum of space you place a blackbody object with (a) a constant (i.e., unchanging energy per unit time) internal thermal energy source, and (b) internal / surface thermal conduction properties such that independent of how energy enters the blackbody, the surface temperature of the blackbody is everywhere the same and you place that object in cold space (no background thermal radiation of any kind), eventually the object will come to a steady state condition — i.e., the object will eventually radiate energy to space at a rate equal to the rate of energy produced by the internal energy source.
