Using Maxwell’s relations derive first and second energy equations. Using first energy equation, show that the internal energy of an ideal gas is independent of its volume.

A diatomic molecule modeled as two point masses,m1 and m2, slightly separated. If the molecule is oriented along y-axis it has kinetic energu K when it spins about the x-axis. What will its kinetic energy be if it soins at the same angular speed about (a). The z-axis b).the y-axis

A fountain shoots water to an height of 12 cm. from a nozzle of 0.60 diameter.
The pump at the base of the structure (which is 1.1 mts underneath the nozzle described above), pushes the water in a pipe of 1.2 cm diameter up to the nozzle at the top.
Calculate what is the relative pressure that the pump has to exert and also the pressure in case the liquid is considered viscous (viscosity=0.89x10*-3 Pascals)
