CHEMICAL CHANGE
1. Melting ice
2. Boiling water
PHYSICAL CHANGE
1. Baking a cake
2. Burning wood
Boiling is a physical change, not chemical.
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
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.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
no. Those are physical changes.
melting any metal is physical. rusting iron is chemical
Its a chemical change. Chemical changes produces a new substance while physical change does not Examples of physical change are ripping paper, breaking a bottle and melting ice. Examples of Chemical change are cooking macaroni, rusting iron and mixing acids and bases to make salt and water
Physical
Boiling is a physical change, not chemical.
Boiling water is a physical change because it does not change the chemical composition of the water.
Ocean water is a substance, not a physical or chemical change.
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Carving pumpkin physical change or chemical change
No, a chemical change is when a substance and forms one or more new substances, it changes its composition. examples: changes in color production of gas formation of precipitate Boiling water is an example of physical change, it can be any phase 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.
To call it an physical or chemical change, we first need to describe both of them briefly. A physical change is the one which does not change the chemical properties of a substance. A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here. So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples) However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)
