∙ 11y agoNo, heating a solution of powdered milk is a physical change, not a chemical change. The milk powder dissolves in water due to its particles separating and spreading out, which is a physical process. Chemical changes involve the formation of new substances with different chemical properties.
Dissolving in water is a physical change because the chemical composition of the substance remains the same. The particles of the substance are dispersed in the water but do not undergo a chemical reaction to form new substances.
Physical. If water evaporates, it is still water. It does not change into a different substance. A Chemical change is when something changes into a different substance. For example, when wood is burned, it changes into a different substance(ash).
No, it is only a physical change since the chemical properties of alcohol do not change.
Yes, the reaction of a substance with water is considered a chemical property. It involves a chemical change where new substances are formed due to the rearrangement of atoms in the reactants. This is different from a physical property, which does not involve a change in the chemical composition of the substance.

Ocean water is a substance, not a physical or chemical change.
Water bubble is a substance not a change.
A reaction with water is a chemical process (or change); but reactivity is a property of a substance.
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Dissolving in water is a physical change because the chemical composition of the substance remains the same. The particles of the substance are dispersed in the water but do not undergo a chemical reaction to form new substances.
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
Yes, a change that produces a new substance is considered a chemical change. This is because the chemical composition of the substances involved is altered, resulting in the formation of different molecules with unique properties.
The change is a physical one because the powder is simply dissolving into the water, and it could be powdered again by removing the water again. The physical properties of the fruit punch are very different, but not a chemical change unless there is a new substance created or precipitated.
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
