    What temperature actually a measure of?

    Sorry guys for being so late in response. Actually i didn't expect such of long and idverse discussion on the seemingly simple concept of temperature. But temperature appears to be a very difficult property to unerdstsnd at sub-particle level and in that term is really cery difficult to define...

    What temperature actually a measure of?

    Hello guys In my previous tags come up with some molecular description of substances. And it has been suggested that temperature, a degree of hotness or coldness is basically, a direct indication of the average kinetic energy of the molecules the body made of. After a deeper look toward this...

    What does high temperature mean?

    oh i think i understand the matter, when temperature increases the available molecular motions speed up i.e they increases their energy from the heat(energy to be correct) supplied to them externally for each degree of freedom the rise in K.Es per unit rise in temperature is 1/2k. And as u...

    What does high temperature mean?

    sorry now my office timings are now over and i have no other access of internet so i will like to keep this matter for tommarow.

    What does high temperature mean?

    does it happen that for a given system with the change in temperature some of its ,degrees of freedoom goes blocked or may increases that could also be an explanation of why the specific heats of substance varies with temperatre?

    your answer has now create one another question in my mind. May i ask it?

    What does high temperature mean?

    dear vodka, ignoring quantum effects, just as in ideal gas we quantify translational kinetic energy average per atom)3/2kt can we say all K.Es to have same values at the same temperature. and doubling temperature will double the other K.Es? Regards

    What does high temperature mean?

    ok i understand what - what contribute, here is one more thing i want to clearfy. does raising temperature raises all types of kinetic energies ( a system posses) in the same way. like doubling the absolute temperature doubles each kind of K.Es? or it depend on a particular system and the...

    What does high temperature mean?

    Responding phinds, as i already emphasized " Let us suppose that i didn't know what was in the two boxes , what conclusion should i draw by seeing their temperature to be different? how do the two systems different on microscopic level." i don't know what is there in the two systems no...

    What does high temperature mean?

    hmmm is this the thing? so does it mean not only the translational kinetic energy contribute to temperature but other types of kinetic energy(vibrational and rotational) too contribute to temperature? for an ideal gas they how translational kinetic energy depends on temperature(or we may...

    What does high temperature mean?

    Thanks DaveC426913 for your support.As far as it seems you have no where in your answers written anything wrong about how the temperature has risen. But the gravity of my question is more towards the the state of hotness than the cause of hotness. Let me take a different example i have a...

    What does high temperature mean?

    Hello All, Suppose i have two identical boxes having sufficient oxygen ( these boxes contains same amount of coal, but one in one box coal is raw while in the other coal is burning ) when i use thermometer, the thermometers reads different readings one is high other is low. Let us...

    Internal energy and state functions

    THANKS! Oh this comes out to be what I was started assuming last night afrer getting the concept of state from my earlier post through simon bridge.. What I now understood is that at a PARTICULAR STATE all the state functions have a UNIQUE VALUE(for each) that gives the discription of the...

    Internal energy and state functions

    Hello all, I have following questions dangling in my mind, with a positive attitude of seeking help i want put them infront you geneus people, in my earlier post i get a good result and now i want to more insight of the very matter. kindly help me. Using the concept of state of system, i...

    Thermodynamical state

    I will further be very thankfull to anybody who could tell me that, if two systems(similar) are at same state, will that mean that all the state functions will have the same value or not? I really very curious to understant. I am sorry for my dull mind:)

    Thermodynamical state

    Ok.., means by just knowing the internal energy of a paeticular well known sysrem, one can not pridict other state functions(their values), the system is in. Can this be finally assumed? Or i can say two systems undegoes same change in internal energy from same initial state may have diffetent...

    Thermodynamical state

    Suppose i have two containers of raw rice of same hybrid (i.e having same internal energy) and i started cooking them using same ingridents but by different mode of heating. If after being cooked to the same level it is found that the change in internal energy in both is the same, now is it...

    Thermodynamical state

    Hi All, During my study of thermodynamics these days I have a little confusion regarding the concept of state of a system and state functions. Here I begin what confuses me. We know temperature, pressure, volume, internal energy, entropy etc. are state functions. 1.I am wondering if...
