Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

A mass of 300g hangs in a spring with a spring stiffness of 40
N/m (same situation as in Exercise 4.6). The mass is
connected to the spring with a weightless cord, the rigidity of
the cord can be considered infinite, ie it is so large that it does
not affect the rigidity of the system. We start with a situation
where the spring is not loaded and the weight is placed at the
end of the spring. So the weight is ground free so that it falls
from a height equal to the length of the string before it starts
to act on the spring. 0 cm, 6.0 cm, 12 cm, 24 cm. That is, for
situations when the length of the cord is 0 cm, 6.0 cm, 12 cm
and 24 cm.
