Complete the passage to explain how the first law of thermodynamics describes what happens to heat added to or
absorbed by a system.
the first law of thermodynamics describes how the heat added to a system is conserved. heat
the internal energy of the system or is transformed into
or both. heat is just transformed, not created
or destroyed.

The correct answer is  "Heat is just transformed, not created

or destroyed".

Explanation:

The first law of thermodynamics describes what happens to heat added or absorbed by a system, in which it is indicated that the work plus the heat in a system is equal to the variation of the internal energy. Therefore the first law of thermodynamics describes how heat is transformed into work or stored in internal energy, not created or destroyed.

Have a nice day!

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
