Do the temperature and the pressure have to be the same everywhere in thermodynamic equilibrium?
Yes both the temperature and the pressure should be same because for a system to be in complete thermodynamic equilibrium both the thermal (in which temperature remains the same) and the dynamic (in which the pressure remains the same) equilibriums should be considered.

What is tmcr bmcr conditions of thermal power plant?
BMCR is the boiler maximum continous rating .It is that the maximum temperature , steam flow or the pressure that is used to generate full load or the bolier can withstand.TMCR is the turbine maximum continous rating .It is that the maximum temperature , steam flow or the pressure that the turbine requires for generating full loadNOTE:BMCR WILL BE MORE COMPARED TO TMCR
What does subline mean?
The definition of "subline" (a term relating to cellular biology) may be found at: http://www.merriam-webster.com/dictionary/subline I am answering here in case you meant "sublime" "Sublime" is a term in chemistry and physics referring to the process in which some materials, given appropriate conditions of temperature and pressure, can change phase directly from a solid to a gas (where most materials under most conditions must pass through the liquid phase when changing from a solid to a gas). Examples are Iodine, which can sublime at room temperature and pressure (note this refers to pure Iodine, not the solution you buy at the drug store), and ordinary water ice, which can sublime under some temperature and pressure conditions, including in a self-defrosting freezer.
What is the centermost layer of the earth?
The inner core is the innermost part of Earth's structure. Composed mainly of nickel iron and heavy metals, it has a temperature of about 5700 deg C, (the same as the surface of the Sun) and is solid because of the pressure. It is heated mainly by radioactive decay, but a small contribution by gravitation pressure is also present.
What is trespa?
It is a flat panel based on thermosetting resins, homogeneously reinforced with cellulose fibres and manufactured under high pressure and temperature. Using special techniques, the panels have an integrated, decorative surface with melamine-impregnated paper.
What is the approximate vapor pressure when the gas condenses at 80oC?
The vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. The vapor pressure depends on the temperature and the substance.
What is the meaning of thermodynamic melting point?
Thermodynamic melting point is the temperature and pressure at which a solid will be in equilibrium with a liquid of the same composition. It is not a single point, rather it is a two-dimensional function of temperature and pressure. For most substances, the effect of pressure is rather gradual so that large changes in pressure are required to cause any significant changes in the melting point temperature.
What is the vapour pressure of liquids?
Vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is a measure of a liquid's tendency to evaporate. The higher the vapor pressure, the more volatile a liquid is.
What is thermodynamic equilibrium in physics?
Thermodynamic equilibrium is a state in which a system is not experiencing any net change in its macroscopic properties over time. In this state, the system's temperature, pressure, and other relevant variables are uniform and do not exhibit any gradients. This concept is important in understanding the behavior of systems in thermodynamics.
What is thermodynamic equilibrium?
At thermodynamic equilibrium the dynamic processes for changes in a system have reached a steady state (not changing with time) where temperature has stabilized to a constant, no heat is being exchanged, no work is occurring, composition is constant (reactants are being converted to products at the same rate that the products are converting back to the reactants), pressure is constant, if there is more than one phase, movement between the phases is balanced (for example evaporation and condensation are occurring at the same rate), and there are no concentration gradients.
What is the triple point for silver?
The triple point refers the temperature and pressure at which the three phases of silver coexist in the thermodynamic equilibrium. The triple point of silver is 1233.95 degrees Celsius.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
How does the vibrational contribution to internal energy impact the overall thermodynamic behavior of a system?
The vibrational contribution to internal energy affects the overall thermodynamic behavior of a system by influencing its temperature and pressure. When molecules vibrate, they store energy which can affect the system's heat capacity and ability to transfer heat. This can impact the system's ability to reach equilibrium and respond to changes in temperature or pressure.
What is equilibrium parameters?
Equilibrium parameters refer to the specific conditions, such as temperature, pressure, and chemical composition, at which a system is in thermodynamic equilibrium. These parameters define the state of the system where the rates of forward and reverse reactions are equal, resulting in no net change in the system's properties over time. Equilibrium parameters are crucial in understanding and predicting the behavior of chemical and physical systems.
What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
What are two factors same for the density of a pure substance to stay constant?
Density is an intrinsic property of each type of material, defined as the total mass divided by the total volume. Obviously, two samples of the material which have the same mass and same volume will have the same density, but that is not that answer to this question. This question is about the thermodynamic state of a material and the answer is temperature and pressure. The thermodynamic state of a system is a set of properties that are reproducible when the thermodynamic variables have been specified. Density is one such property. Specifying the temperature, pressure and specifying the quantity and type of material of a system determines density at equilibrium. The equilibrium condition is critically important in that assertion. It is a fundamental premise of thermodynamics that the state of a simple system at equilibrium can be completely characterized by specifying two independent property variables, such as temperature and pressure, and the quantities of the chemical constituents. Any system then with the same thermodynamic state has the same intrinsic properties such as density, heat capacity, thermal conductivity, viscosity, and other characteristics.
What does the adiabatic process graph illustrate about the relationship between temperature and pressure in a thermodynamic system?
The adiabatic process graph shows that as temperature increases, pressure also increases in a thermodynamic system. This relationship is due to the fact that in an adiabatic process, no heat is exchanged with the surroundings, so changes in temperature directly affect pressure.
