An ice cube is placed on a kitchen counter. which best describes heat flow in this situation?

a. heat flows from the ice to the counter, causing the molecules in the counter to move more quickly.
b. heat flows from the ice to the counter, causing the molecules in the counter to move more slowly.
c. heat flows from the counter to the ice, causing the molecules in the counter to move more quickly.
d. heat flows from the counter to the ice, causing the molecules in the counter to move more slowly.

Option (d) is the correct answer.

Explanation:

Temperature of ice is low and the temperature of counter is high. Therefore, to melt ice it requires absorption of energy. Hence, heat from the counter will provide energy to melt ice.

When heat gets transferred from the counter to the ice, then there will be decrease in energy of counter because heat is flowing out. As energy decreases there will be a decrease in the motion of particles.

Thus, we can conclude that heat flows from the counter to the ice, causing the molecules in the counter to move more slowly.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
