What happens to ice when heat is applied?

When heat is applied to ice, the thermal energy causes the molecules in the ice to vibrate more rapidly. As the temperature rises to the melting point of ice, which is 0 degrees Celsius (32 degrees Fahrenheit), the ice transitions from a solid state to a liquid state through the process of melting. During this phase change, the ice absorbs heat without a change in temperature until it is fully converted into water. This phenomenon aligns with the principles of thermodynamics, specifically the concept of latent heat, which describes the energy required to change a substance from one phase to another without altering its temperature. Hence, the correct answer highlights the process by which ice, upon receiving heat, transforms into liquid water.
