I am getting the bulk modulus from fitting the equation of states and calculating the elastic constant. It seems that there is some relationship between bulk modulus B and elastic constant Cij, B=Cij/9,where i,j run from 1 to 3.
But my result is far away from this, say B=50 from fitting EOS and...
The questions is that
The equation of state (the equation relating pressure, volume, and temperature) for an ideal gas is pV=nRT, where n and R are constants.
a.) Show that if the gas is compressed while the temperature T is held constant, the bulk modulus is equal to the pressure.
b.)...
An incerase of pressure of one atmosphere, causes a reduction of 49*10^-^6m^3 in a volume of 1m^3 Give the value of the bulk-modulus of water. Calculate the denisty of the water of a lake, at a depth of 200 metres, assuming that the density of water is 1000kgm^-^3 at the surface...
When I calculate the Bulk modulus for a metall with the free electron model
I get a value that is twice the experimental value.
I find this strange.
With the free electron model i don't get the contribution from the ion cores and the bound electrons, right?
Do these have a negavite...
