Can we consider temperature in general as "property" without even been associated to well defined states of matter.
Like the boiling and melting points.

Temperature is defined by the relationship between the internal energy and the entropy of a sample of matter. If I'm understanding your question properly, that makes the answer "yes" - but you would be better off spending some time understanding what temperature is and how it is related to entropy.

Taking the definition of temperature as the measure of average kinetic energy per particle,it is considered as property of material when associated with a well defined state of that material like it's boiling point ,say.but the question is heat transfer cannot be stopped,right?,so if we can say the universe is going towards a one temperature after sufficient time makes it property of well divided regions of universe that are at given one temperature,but also a property of the whole universe when reach the one common temperature,so we can consider it as property as long as universe is not well defined.
This is my question .

It is better to define temperature as a thermodynamic state function characterising a thermodynamic equilibrium.

So the answer to my question that temperature can be considered as property in general is right?

I would say that a condition under which a substance is being kept (for instance its temperature) is not a 'Property'. Examples of properties would, imo, be its boiling point, its resistivity or its bulk modulus. Two different substances, with many differing properties can be side by side, in the same water bath and at the same Temperature.

Temperature does indeed have a relationship with matter... it even has a relationship with wave matter!

Temperature ordinarily for physicists is thought about in terms of the equipartition. The energy of a single particle in terms of temperature is

[tex]E = \frac{3}{2}k_BT[/tex]

The Virial theorem, also says something about relating the temperature of a system to the average kinetic motion of its constituents and can loosely be though of as

[tex]k_B T = \frac{1}{2} \mathbf{p} \cdot \mathbf{v}[/tex]

Thirdly, temperature can be associated to the wave property of matter known as the thermal deBroglie relation.
 

Related to Temperature as a property of matter

1. What is temperature?

Temperature is a measure of the average kinetic energy of the particles in a substance. In simpler terms, it is a measure of how hot or cold a substance is.

2. How is temperature measured?

Temperature is typically measured using a thermometer, which contains a liquid (such as mercury or alcohol) that expands or contracts with changes in temperature. Digital thermometers use electronic sensors to measure temperature.

3. What are the different units for measuring temperature?

The most commonly used units for measuring temperature are degrees Celsius (°C) and degrees Fahrenheit (°F). In scientific contexts, Kelvin (K) is also used. 1°C is equal to 33.8°F and 0°C is equal to 273.15 K.

4. How does temperature affect matter?

Temperature can affect matter in a variety of ways. It can cause substances to expand or contract, change state (such as from a solid to a liquid), or undergo chemical reactions. Temperature can also impact the behavior of particles in a substance, such as increasing their speed and causing them to collide more frequently.

5. What is absolute zero?

Absolute zero is the lowest possible temperature, where the particles in a substance have no kinetic energy. It is equivalent to 0 K or -273.15°C. This temperature has never been reached in a laboratory setting, and some theories suggest that it may be impossible to reach absolute zero.
