Answer:
The correct answer is Option B. The bonds between water molecules.
Explanation:
- The melting of an ice cube in a thermos with a closed lid is an example of an isolated system in which there is no exchange of heat or mass between the system and its surroundings.
- Heat is a thermodynamic quantity that can be used to do work. It is not necessary that heat will increase the temperature of a system. Sometimes heat is hidden in the form of latent heat.
- The latent heat breaks the hydrogen bonds that bind the molecules of water. There is no rise in temperature.
- The energy gets absorbed into the water molecules.
