... The low temperature specific heat of graphene shows a linear dependence on temperature (see Figure 1) which then becomes quadratic for temperatures greater than 100 K. Can you explain this behavior based on your knowledge of the dispersion relation of graphene (see HW 2 for a plot) and the expressio ...

... HoT - Ho298 is the enthalpy at the standard state T less the enthalpy at the standard state at 298.15 K. (GoT - Ho298)/T is the Gibbs energy function and is equal to (HoT - Ho298)/T - SoT. This function is tabulated because it shows greater linearity than GoT thus facilitating interpolation between ...

Measuring Temperature
... Temperature is the main physical quantity which describes the state of a thermodynamic system. The measurement of temperature is based on the fact that all objects - and consequently also temperature sensors - are exchanging energy with their surroundings. There are three ways to exchange energy: · ...
