Beating egg whites to make then stiff it is a physical change. The proteins forming the substance of the egg white are complexly folded molecules and the beating causes them to partially unravel. as they do this they can form a net which can capture tiny pockets of air which increases their volume and makes them appear white. This physical change will partially revert if the beaten whites are left to stand for too long before cooking.

When sugar canalize on being heated above its melting point is physical change or chemical?

If water if heated and changed into steam is this a chemical or physical change?
The change of water into steam is a physical change. This is because the molecules of water are simply being rearranged into a different state (liquid to gas) without undergoing any chemical reactions.
Is hot water an chemical or physical change?
Heating water to make it hot is a physical change, as the water's chemical composition remains the same. The change in temperature simply affects the kinetic energy of the water molecules, causing them to move faster and appear hot.

When water is heated and changed into o steam is that a chemical or physical change?
The change from water to steam is a physical change. It involves a change in the physical state of the substance without any alteration in its chemical composition. The water molecules are still the same, they are just being converted from a liquid to a gas state.
When heated to decomposition calcium chloride produces chlorine gas is it physical or chemical?
The production of chlorine gas when calcium chloride is heated to decomposition is a chemical change. This is because a new substance (chlorine gas) with different chemical properties is formed as a result of a chemical reaction taking place between the calcium chloride and heat.
Is a wet handkerchief is physical or chemical change?
A wet handkerchief is a physical change. The water has only physically changed the state of the handkerchief by being absorbed, but the handkerchief itself has not undergone a chemical transformation.
