If you had spent time learning and thinking, you might know by now.Instead, you spend time saying stupid things like
Quote from: Spring Theory on 27/05/2022 14:58:59One of the most useful tools in analyzing physics is working in natural units. This basically sets your constants equal to 1 (more to that though). Numerically, yes, but you have to transfer the dimensions of your constant to some other quantity, and of course it can only work for one constant at a time.

I bend over backwards here trying to help you guys understand concepts and be productive to the topic but the typical response is just an unproductive, smart ass quip.What a waste of time and effort. You guys deserve neither.
It just reveals what many of you people are here for, trying to prove how much you know about science. What a farce.

What's temperature,
What's temperature, if you have to explain to an adult?

Quote from: hamdani yusuf on 31/05/2022 23:07:01What's temperature, if you have to explain to an adult?We answered that.You still don't know what temperature is.It may be possible to deduce something from those to observations.
Quote from: Eternal Student on 26/05/2022 01:08:07 I am a little curious about where you are going with this thread. Is there something you think temperature should be?I just try to understand what temperature is by relating it with other things I already understood. The description by Wikipedia below requires the understanding of other concepts first. I want to understand how those concepts are related to each other consistently and useful to explain and predict observations and experimental results.Quotehttps://en.wikipedia.org/wiki/TemperatureTemperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter. Temperature should not be confused with heat.International Kelvin scaleMany scientific measurements use the Kelvin temperature scale (unit symbol: K), named in honor of the physicist who first defined it. It is an absolute scale. Its numerical zero point, 0 K, is at the absolute zero of temperature. Since May, 2019, its degrees have been defined through particle kinetic theory, and statistical mechanics. In the International System of Units (SI), the magnitude of the kelvin is defined through various empirical measurements of the average kinetic energies of microscopic particles. It is numerically evaluated in terms of the Boltzmann constant, the value of which is defined as fixed by international convention.[5][6]Statistical mechanical versus thermodynamic temperature scalesSince May 2019, the magnitude of the kelvin is defined in relation to microscopic phenomena, characterized in terms of statistical mechanics. Previously, since 1954, the International System of Units defined a scale and unit for the kelvin as a thermodynamic temperature, by using the reliably reproducible temperature of the triple point of water as a second reference point, the first reference point being 0 K at absolute zero.[citation needed]Historically, the triple point temperature of water was defined as exactly 273.16 units of the measurement increment. Today it is an empirically measured quantity. The freezing point of water at sea-level atmospheric pressure occurs at approximately 273.15 K = 0 °C.The article says that temperature is a measure of the average kinetic energy of the atoms or molecules in the system. But we know that not all kinetic energy of the atoms or molecules are in the form of heat which contribute to the system's temperature. How they move also affects the temperature measurement of the system. Uniform rotation of a solid object can make it have a very high average kinetic energy. But usually it's not called a hot object.Quotehttps://en.wikipedia.org/wiki/HeatIn thermodynamics, heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter.[1][note 1]Like thermodynamic work, heat transfer is a process involving more than one system, not a property of any one system. In thermodynamics, energy transferred as heat contributes to change in the system's cardinal energy variable of state, for example its internal energy, or for example its enthalpy. This is to be distinguished from the ordinary language conception of heat as a property of an isolated system.The quantity of energy transferred as heat in a process is the amount of transferred energy excluding any thermodynamic work that was done and any energy contained in matter transferred. For the precise definition of heat, it is necessary that it occur by a path that does not include transfer of matter.[2]Though not immediately by the definition, but in special kinds of process, quantity of energy transferred as heat can be measured by its effect on the states of interacting bodies. For example, respectively in special circumstances, heat transfer can be measured by the amount of ice melted, or by change in temperature of a body in the surroundings of the system.[3] Such methods are called calorimetry.

In principle, I agree with Wikipedia article which says that temperature is a measure of the average (internal - as Alan mentioned) kinetic energy of the atoms or molecules in the system.
