Frank wrote several statements to summarize the relationship between the first and second laws of thermodynamics. 1 - Thermal en

ergy is conserved. 2 - Some thermal energy is lost and some is used to do work. 3 - Thermal energy flows from areas of higher to lower temperatures. 4 - Thermal energy can be transferred and transformed. Which statement relates most directly to the second law?

According to the second law, heat which is also referred to as thermal energy can be completely converted into work. 
The second statement is much related directly to the second law.
We can say that some energy is lost while other is used to do work.

Answer:

Some thermal energy is lost and some is used to do work

Explanation:

The first law of thermodynamics sates that the energy is neither created nor destroyed. This law basically states the conservation of energy.

Mathematically, it can be written as :

\Delta U=Q-W

Where,

\Delta U is the change in internal energy

Q is the heat absorbed

W is the work done

Second law states that for an isolated system the entropy should increase or remains the same. It will never decrease.

The relationship between the first and the second law is  (2) " Some thermal energy is lost and some is used to do work ".

One of two nonconducting spherical shells of radius a carries a charge Q uniformly distributed over its surface, the other carri
lisabon 2012 [21]

Answer:

Explanation:

A ) The spheres are non conducting , charge will not move on the surface so neutralization of charge by + ve and - ve charge is not possible. Charges will remain intact on them . The electric field inside them will be zero . Electric field outside shell  will not be spherically symmetrical . Lines of force will emanate from the surface of positively charged shell  outwardly oriented  and end at negatively charged shell .

B )

distance between the centres of spherical shell

= 2 a

potential energy of charges

= k q₁ x q₂ / R

= k x - Q x Q / ( 2a )

= - k Q²/ 2a

So work needed to separate them to infinity will be equal to

= k Q²/ 2a
