boiling a phyisical change... but not chemical ( making it a new substance )
Vaporization.
The process is evaporation
Below boiling point of water, water gets changed from liquid form into vapour form. This is called as vaporization. Thus change of state is possible even below boiling point. An liquid can be changed into solid at its freezing point. This is also a change of state.
The change in physical state from liquid to gas occurring throughout the liquid is called boiling. It occurs at boiling point of a liquid or when the pressure of the surroundings is reduced as per its boiling point. It boils with the use of vacuum pump and at high altitudes. Boiling Vaporization is the change in state from a liquid to a gas. Evaporation and boiling are the two types of vaporization. You are describing boiling. boiling A+: Condensation
The tendency of a solute to change the boiling point of a solvent is called boiling-point elevation. This occurs because the presence of the solute disrupts the solvent's ability to form vapor, therefore requiring more heat to reach the boiling point.
Melting.
The boiling of silver is a physical change, in order for something to be called a chemical change, something completely new not only form, but chemical composition as well. Boiling silver produces silver gas but it still has the original chemical makeup.
The word "change" can be used with the phrase "of state" to describe a transition or transformation from one condition or form to another. For example, "The boiling water underwent a change of state to become steam."
The change of state directly from solid to gas is called sublimation, and the change from gas to solid is called deposition.
it is called a meniscusal form
A change in temperature or pressure can affect the state of matter without altering its chemical composition. For example, melting ice to form liquid water or boiling liquid water to form steam are changes in state of matter that do not change the chemical makeup of water molecules.
