Chapter 18, Problem 39A

To determine

To identify: Whether crushed ice melts faster than the same mass of ice cube.

Answer to Problem 39A

Crushed ice will melt faster than the same mass of ice cube.

Explanation of Solution

Introduction:

Heat transfer:

The heat energy is transferred from the surface of any object. It is directly proportional to the surface area through which heat is transferred.

It means the object having higher surface area transfer heat relatively faster than the object with lesser surface area.

Ice melts when it absorbs heat energy from the surroundings.

In the given question, the crushed ice has larger surface area than the ice cube of same mass.

Therefore, there will be more area is exposed to surrounding to absorb heat. It means more heat will be absorbed in crushed ice from the surrounding than the ice cube.

Hence, the crushed ice will melt faster.
