Question

What changes occur at the molecular level when butter melts in a hot pan?

A.
the motion of the butter molecules remains the same

B.
the motion of the butter molecules increases

C.
the motion of the butter molecules decreases

D.
the motion of the butter molecules stops completely

Answer 1

The Answer is B. The Motion of the butter molecules remains the same

Answer 2

Answer:B. the motion of the butter molecules increases

Explanation:The melting point of the butter lies between 32°C to 35°C, it has no sharp melting point because it is chemically a mixture with no definite composition.

When the heat is supplied to the butter then its molecules gain the energy and their kinetic energy increases which leads to the change in its phase.
