Explanation:
The first law of thermodynamics is given by :

Here,
Q is amount of heat added to the system
is change in internal energy
W is amount of work done by the system
It is clear that the energy can be neither created nor destroyed, it remains conserved. Hence, first law of thermodynamics shows that conservation of energy.

Let the tension in the thread will be at angle theta
now by force balance in x and y directions we can say



now for the height of the kite we can use



<em>so it will be at height 32.23 m from ground</em>
It condenses into liquid water.
