Two interacting blackbodies (one inside another) - when will thermal equilibrium be attained? [closed]
As I understand it, an ideal blackbody absorbs (and subsequently starts emitting) all incoming radiation. In typical setups like determining a planet's temperature given its albedo and distance from a ...

Can a body be in thermal equilibrium at a different temperature from surroundings?
As per my knowledge bodies attain constant temperature (thermal equilibrium with surroundings) when they absorb and emit energy at equal rates.
Let us say temperature of surroundings is T1.
We have a ...

Zeroth Law of Thermodynamics on Thermometer
I'm confused by how thermometer works based on The Zeroth Law of Thermodynamics. The Zeroth Law of Thermodynamics said that
"If a body, A, be in thermal equilibrium with two other bodies, B and ...

Work obtained during isentropic expansion in the Carnot cycle versus the work done to gradually lower the outside pressure
We have a Carnot cycle and lets say it is in thermal and mechanical equilibrium with the surroundings before the beginning of the process. I am using the convention that heat brought to the system is ...

What happens to entropy and energy when you inject heat into 2 systems in thermal equilibrium?
Below we have a system A and B in thermal equilibrium. What happens to the entropy and energy of the systems when you inject heat into system A and let it equilibriate further? I know that heat will ...

Thermal equilibrium, heat and temperature [duplicate]
I am just studying thermodynamics for the first time and confused between these three terms
Temperature is defined in terms of thermal equilibrium (from zeroth law of thermodynamics) and thermal ...

Total temperature when combining two systems of unequal temperature [closed]
I know that intensive properties a characterised by the fact that when you combine two systems (A and B) that have the same value of an intensive property (for example same Temperature) the combined ...

Same temperature implies thermal equilibrium
A particularly weak formulation of thermodynamics is
Two bodies are said to be in thermal equilibrium if no heat transfer occurs when they are put in diathermal contact. Thermal equilibrium is an ...

Does physical equilibrium occur at specific temperature and pressure?
Does physical equilibrium occur at only specific temperature and pressure? Like does equilibrium occur only at $ 1 atm $ and $0⁰C$ between water and ice? If I change temperature or pressure will the ...

An axiomatic approach to thermodynamics
I have been working on an axiomatic approach to thermodynamics, and tried to follow the footsteps of Theodoro Frankel using his little book, The Geometry of Physics.
The passage appears before ...

Temperature and pressure being equal at equilibrium (from first law of thermodynamics)
I have a question in which an insulated container of gas with volume $V$ is divided into two parts $V_1$ and $V_2$ by a movable barrier through which energy can pass, and need to show that, using the ...

Is energy distributed equally in system in thermodynamic equilibrium?
When a thermodynamic system is in equilibrium, it is said to have equally distributed energy, so that the entropy is highest possible, also, the temperature is same everywhere in the system. But ...

Does true thermal equilibrium take an infinite amount of time to reach? That is to say, is thermal equilibrium reached asymptotically?
I intuitively visualize thermal equilibrium as the gradual homogenization of temperature, but I can't see how it would actually reach it in a finite amount of time.

How does one show that $\beta$ is the same for different substances in thermal equilibrium?
In the section regarding quantum statistical mechanics, Griffiths uses the method of Lagrange multipliers to calculate the most probable energy configuration $(N_1,N_2,\dots)$, where $Q(N_1,N_2,\dots)$...

What is temperature: function of energy or the value of this function in thermal equilibrium?
As far as I remember, many textbooks on statistical physics introduce temperature as a condition of equilibrium of a composite thermodynamic system. E.g., if the system consists of two parts with ...
