What is relation between thermal conductivity and viscosity?

Answer 1

The equation for specific heat capacity allows you to work out the energy produced. If the value in J or kJ is positive then the reaction is exothermic, because it produced an excess of energy. If the value is negative then of course it's endothermic, because it requires an input of energy, so that the reaction even takes place.

Answer 2

Generally, no. Specific heat has to do with thermodynamics, which is an equilibrium science. Thermal conductivity deals with the transport of heat (i.e., how quickly it can absorb) vs. how much it can absorb for heat capacity. No formal connection has been made yet, though there is some promise in the realm of nonequilibrium thermodynamics, which deals with the transport of material properties using some of the basic thermodynamic approaches and assumptions. This has yet to be extended to open systems, however, so most of the advances have nothing to do with real scenarios.

In statistical mechanics, the heat capacity is proportional to the variance of the internal energy of a system, so if a system fluctuates about its equilibrium value to a higher extent (due to lower energy level differences), then it will have a higher heat capacity, as more of its energy levels can be filled up. Potentially, this could lead to a connection between the heat transfer, as when higher energy levels are more easily accessed, the heat transfer rate should increase as well, since more perturbations/fluctuations through the system should facilitate this. Like I said, though, no formal connection has yet to be made. Perhaps you are the one to do it!

Answer 3

specific heat is directly proportional to heat capacity

Answer 4

inversly proportional to each other
