Question

Consider the following statements. A. Heat flows from an object at higher temperature to an object at lower temperature; B. Heat flows from an object with higher thermal energy to one with lower thermal energy; C. Heat flows from an object in liquid state to an object in solid state. Which statements are true?

Answer 1

Answer:

A. Heat flows from an object at higher temperature to an object at lower temperature

Explanation:

The option A obeys the 2nd law of thermodynamics. The heat will flow from the object at higher temperature to the object at Lower temperature till they reach an equilibrial state.

Heat doesn’t necessarily flow from an object with higher thermal energy to an object with lower thermal energy because an object has a higher thermal energy when it’s mass is more than the other. This makes B wrong.

C is wrong because heat moves from an object with higher temperature to objects with Lower temperature regardless of the state of matter.
