Why do ice pops melt?


States of Matter

  • Ice pops are solid in the state.
  • Every object has a definite state known as the state of matter.
  • Ice pops are frozen in nature and hence are solid objects.
  • For any object to be solid, it requires a close and tight bonding between its atoms.
  • When these atoms are far apart from each other, the state of matter begins to change.

Atom is the smallest unit of a matter. There are three states of matter, solid-state, liquid state or gaseous state.

  • In a solid state, every matter has a definite shape because of closely bound molecules.
  • A liquid state is a free-flowing state with a greater amount of space between the constituent molecules. They have the ability to take the shape of any vessel in which they are present or can be said to possess the ability to change shapes depending on the container in which they are present.
  • The gaseous state has the most space between its constituent particles and therefore has no defined shape or structure. They move around in the environment freely with the least restriction and occupy as much volume as possible.
  • It is possible for any object or matter to change its state under predefined conditions like water can be frozen to form ice. This process involves the conversion of water in its liquid state to water in its solid state i.e., into ice.  On the other hand, when allowed to boil, water molecules start evaporating and turn into water vapour, which is water in the gaseous state.

Why Do Ice Pops Melt?

  • Ice pops are solid in nature, which means they have closely bound molecules present within them.
  • However, when we take them out at the normal temperature, there is an exchange of heat that takes place between the cold ice pop and the warmer surrounding environment.
  • Ice pops start absorbing heat from the surrounding environment causing the bonds within to break and the ice to start melting.
  • This change in the bonding of molecules results in the change of state i.e., change from solid to liquid.
  • Hence, ice pops start melting due to changes in the internal energy or bond present between each molecule.

Fun Facts:

  1. Water starts freezing at the temperature of 0°C.
  2. Water starts evaporating at the temperature of 100°C.
