Van der Waals equation

Andrews experimental PV curve and state of continuity The slope of tangent drawn on critical point is opposite on either side of this point. The isothermal curve touching the critical point is critical isothermal. The temperature, pressure and volume corresponding to critical point are known as critical temperature (T c ), critical pressure (P c ) and critical volume (V c ) respectively. P c , V c and T c are combindly known as critical constants. Conclusion of Andrews experimental curve Any gas can be liquified below its critical temperature. Every gas has a critical temperature above which the gas can not be liquified by increasing pressure. At critical temperature, the density of liquid and its saturated vapour are equal. Above this temperature we can not distinguish between the two states. Near critical temperature, the compressibility of gas is very high and it become infinitive at critical temperature. Above critical temperature, the gas behaves as permanent gas....

Virial equation of state and Boyle temperature

Ideal gas An ideal gas is a gas which satisfy Boyles’ and Charles’ law for all the values of pressure, volume and temperature completely. Equation of state of an ideal gas for 1 gm molecule or 1 mole is PV = RT. In deriving this equation it was assumed that The size of gaseous molecules are infinitely small, so they do not occupy any space. There is no attractive or repulsive force between the gaseous molecules, so they have only kinetic energy, not potential energy. Deviation from perfect gas equation No gas is ideal or perfect, because no gas follow the ideal gas equation PV = RT at all conditions. The gases which liquified easily show more deviation from the ideal gas equation. For every gas there is a temperature at which the value of PV remain almost constant with increase in P and the value of PV increases at very high pressure. This particular temperature is known as Boyle temperature (T B ). Below T B , PV first decreases with increase in P, reaches to a minimum v...

Electric field due to an infinitely long straight uniformly charged wire | Electromagnetics | Electrostatics

Electric field due to an infinitely long straight uniformly charged wire The space around a charged particle in which another charge experience a force is known as electric field. The electric field at any point due to infinitely long straight wire varies inversely with distance from the wire. Electric field at P due to charge dq of length dy                            The charge on length dy, dq = λ dy                          This electric field will be along MP Total electric field at P                               Due to symmetry                                      ...
