When heat is converted into another form of energy, the total amount of energy is constant. which law best illustrates this statement? the first law of thermodynamics the second law of thermodynamics the third law of thermodynamics none of the above

The correct option is (A) the first law of thermodynamics

Explanation:
The first law of thermodynamics takes the idea of law of conservation of energy and modify it for thermodynamics systems. It is the total internal energy of the systems equals to the amount of heat added "to" the system and the workdone "by" the system given as:
ΔU = Q - W
Q = heat added TO the system
W = work BY the system
ΔU = Total internal energy

But the total internal energy is CONSERVED; it means that energy cannot be created or destroyed; it can only be transformed from one form to another. Hence the correct option is (A).

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

Iwould sure like to answer your question but i honestly just don’t know
