The dusting of hydrogen into helium. HOPE THIS HELPEDD
Answer:
The value is
Explanation:
From the question we are told that
The mass of the external weight is
The height through which the mass drops is
The number of revolution made is
The diameter of the free moving piston is
The distance moved by the free moving piston is
The atmospheric pressure is
Generally the workdone by the external weight is mathematically represented as
=
=
Generally the workdone by the free moving piston is mathematically represented as
Here A is the cross-sectional area with value
So
=>
So
The net workdone is mathematically evaluated as
The negative sign shows that it is acting in opposite direction to
So
If it follows the 1st law of thermodynamics it would also remove heat of 314J from the food inside the refrigerator.
