When two substances in thermal contact starting at different temperatures reach the same temperature their condition of thermal balance is called thermal?
Thermal equilibrium?
Explain what happens when two objects at different temperatures are in contact?
Heat energy flows form the warmer object to the cooler object, and their temperatures change toward each other, so that the difference in temperatures decreases.
Why do different surfaces have different temperatures?
Why do they have different surface temperature
What is thermodynamic temperature scale?
The thermodynamic temperature scales are based on the third law of thermodynamics:The entropy of a system approaches a constant value as the temperature approaches zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has.The two commonly used thermodynamic temperature scales are Kelvin (K), which has temperature increments the same size as Celsius and Rankine (°R), which had temperature increments the same size as Fahrenheit.The thermodynamic temperature scales are further defined by extrapolation of the values PV at given temperatures as pressure approaches zero and thus the ideal gas law becomes a better and better approximation.
Why don't different objects heat at the same rate?
Different objects may have different temperatures
Which is hotter f or c?
Neither is hotter. They are different scales and use different measurements for heat. 25C is hotter than 25F, but they are different temperatures.
What is thermodynamic equilibirium?
Thermodynamic equilibrium is achieved when all processes in a system are occurring at the same rate in the forward and reverse directions. When this happens the chemical potential in different phases and of different compositions remains constant. For example: condensation is occurring at the same rate as evaporation, products are being formed from reactants at the same rate that the products are reverting to the original reactants. Solids are dissolving at the same rate as they are being deposited from solution, heat is being absorbed at the same rate that it is being radiated, etc. A system that is in thermodynamic equilibrium experiences no changes in phase, composition, temperature, or pressure when it is isolated from its surroundings.

Does density of ice change at different temperature?
Temperatures below freezing can form ice, and keep it frozen in dynamic equilibrium. Temperatures above freezing can melt ice, and the hotter it is, the faster it will melt.
Can metamorphic rocks be metamorphosed?
Yes they can, the mineral assemblage in a metamorphic rock reflects and equilibrium state pertaining to the temperatures and pressures to which it has been subject. If the rock is subsequently taken to a different Pressure/temperature environment, an new equilibrium mineral phase will start to develop.
What is heterogeneous equilibrium?
heterogenous equilibrium is where there are different phases involved in the reaction.
What needs to happen for thermal energy to be transferred and what needs to happen at thermal equilibrium?
You have to have two objects at different temperatures near each other, when two or more objects have the same temperature.
Which is a characteristic of chemical equilibrium but not physical equilibrium?
the reactants and products are different substances
What are the different kinds of measurements?
nonstandard and standard measurements...
What are the measurements of a car?
Each car is different. The measurements of a Smart Car would be different from a SUV.
Why do the fractions separate at different temperatures?
Because they have different chemical properties and boil at different temperatures
