Answer:
A). The first law describes how thermal energy is conserved but not the direction it moves.
Explanation:
Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).
As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.
Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy. Therefore, option A is the correct answer.
The first law of thermodynamics describes the conservation of heat energy but not the direction it moves. Option A correct.
First law of Thermodynamics:
It states that the energy cannot be produced or destroyed it just change from one form to another.
Heat is a form of energy and thus, follow the energy conservation principle. So, heat can be change into mechanical energy.
The second law describe the direction of movement of heat.
Therefore, option A is the correct answer.
