Thanks Mathman, and yes,Of course iv checked wikipedia b4 posting that question! In wiki it is just the explanation of the terms involved, ie"the ratio of the heat conduction rate to the rate of thermal energy storage", is not that pretty obvious just looking at the equation? but what i want to...

What is Fourier number?? What exactly is Fourier number? I kno its Thermal diffusivity*time/square of radius. But what exactly is the meaning of Fourier number? For eg: Why do we calculate Fourier number for finding out the lumped heat in solids?

Oh yes, that's a really nice explanation, thank u mapes :-)

I do understand the definition of specific heat, but I still don't understand y Cp is greater than Cv.

hi Mapes, I guess i understood the specific heat thing. So specifiv heat is inversely proportional to density, so with constant pressure when volume increases, density decreases, so specific heat increase. ie Cp increase with increase in volume- is that the concept?

Hi, could you pls explain what's difference b/w PdV and VdP? Are both work? if so how are they different. Also mc(p)T = mc(v)T+PV This is the equation my lecturer told for enthalpy(mc(p)T). So how is c(p) and c(v) related? i just dnt get the equation
