Is the heating of a solution of powdered milk a chemical change?
If it is a chemical change it will have a change in color (not meaning food coloring was added) precipitate (solid) was formed, release of gas, new substance was formed, temperature change. If something is baked it was a chemical change
Dissolves in water chemical change or physical?
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.
Is juice freezing a chemical change?
No, it is only a physical change since the chemical properties of alcohol do not change.
Is evaparation a physical or chemical change?
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).
Is Reacts in water is a chemical property?
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.
Is the heating of a solution of powdered milk a chemical change?
If it is a chemical change it will have a change in color (not meaning food coloring was added) precipitate (solid) was formed, release of gas, new substance was formed, temperature change. If something is baked it was a chemical change
Is ocen water a physical or chemical change?
Ocean water is a substance, not a physical or chemical change.
Are water bubbles chemical or physical change?
Water bubble is a substance not a change.
Is react with water is chemical change or property?
A reaction with water is a chemical process (or change); but reactivity is a property of a substance.
Is spilling water a chemical change?
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.
Dissolves in water chemical change or physical?
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.
How can volume change if a substance undergoes a chemical change?
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
Is it correct to say that dissolving a packet of juice powder in water makes a new substance such as fruit punch so it must not be a physical change?
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.
Does a physical change make the substance that undergoes it a different substance if not then what can change?
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
Is juice freezing a chemical change?
No, it is only a physical change since the chemical properties of alcohol do not change.
Is evaparation a physical or chemical change?
