Which best describes heat?
A. energy that is carried by electric and magnetic fields
B. energy that decreases as a car slows to a stop
C. energy that increases as a book is lifted to a higher shelf
D. energy that flows from a hot mug of tea to a cold hand
Answer (1)
Heat is best defined as energy that flows from a hot object to a cold one, such as from a hot mug of tea to a cold hand. This transfer occurs due to a temperature difference and ceases when thermal equilibrium is reached. Understanding heat involves recognizing how energy moves between objects of varying temperatures. ;
