A physical change. Changing H2O from a solid to a liquid or a liquid to gas does not cause any chemical change as in the end you still have H2O.
The time to change phase from solid to liquid to gas is entirely dependent on the energy input. At a great enough input of energy the change can be almost instantaneous. Also, the change depends on the substance that is being changed from solid to liquid to gas.
Melting, the phase change from a solid to a liquid, is considered a physical change rather than a chemical change because when the phase change takes place, the substance that was melted does not change its chemical composition, and the process could be reversed to get the original condition of the substance by freezing (liquid-solid).
When ice cream melts, it undergoes a physical change from a solid to a liquid state due to an increase in temperature. This change does not involve any chemical reactions, as the composition of the ice cream remains the same.
The change that takes place when sugar is heated to form a thick, colorless liquid substance is a physical change. This is because the molecular structure of the sugar remains the same even though its physical state has changed from solid to liquid.
A physical change from solid to liquid state is caused by an increase in temperature, which provides enough energy to overcome the forces holding the solid particles together. This causes the solid particles to gain enough kinetic energy to break free from their fixed positions and move more freely, resulting in the transition to a liquid state.
Heat of fusion.
because solid are rigid while liquid are not

A phase change is when matter changes into another form but keeps its properties.For example, ice melting into water is an example of the phase change melting.The main types of phase changes are melting, vaporization, freezing and condensation.- Melting is when a solid turns into a liquid.- Freezing is when a liquid turns into a solid.- Vaporization is when a liquid turns into a gas. Boiling is a form of vaporization when the change takes place throughout the liquid. Evaporation is a form of vaporization in which the phase change takes place only at the top of the liquid.- Condensation is when a gas turns into a liquid.- There is also sublimation, which is when a solid turns directly into a gas.- Deposition is when a gas turns directly into a solid.

Liquid. There may be solids in chunkier tomato sauce though.
It takes the shape of its container, like a liquid. It is not a solid because it takes the shape of its container, unlike a solid. Not a gas because you can see it
When a solid turns to liquid, it absorbs energy in the form of heat. This heat causes the solid's particles to gain enough energy to break free from their fixed positions and move more freely, transitioning them into a liquid state.
The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid analogous to melting takes place. Heat is required to break the bonds holding the molecules in the solid together. At the same time, heat is given off during the formation of new solute -- solvent bonds.
