B.from a hotter object to a colder object
C.in both the directions
D. heat never flows from one object to other​

Answer 1

Answer:

Heat always flows from a hotter object to a colder object

Explanation:

• The second law of thermodynamics explains that an isolated system’s entropy will never decrease over time.
• Consider, two systems with temperature differences that are in constant contact with each other, then the heat will always flow from one to another until both the systems reach thermal equilibrium with each other.
• According to the second law of thermodynamics, heat will always from higher temperature to lower temperature, since the entropy never decreases over time.

Answer 2

Answer:

heat flows from the warmer sides
