Antiacid tablets are materials not changes; the action of tablets itself is a chemical change.
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
It's a physical change because salt stays the same when it is put in the water. Even though you can not see the salt, it's still there. This will also happen if you put sugar in water.
The compsitions stays the same :0
It will undergo a physical change.
a physical change happens when something is changed physically, for example, snapping a twig or popping a balloon is physical change, but actions like burning wood or cooking an egg are not physical.
yes
It is a physical change, known as a phase transition (see related links below).There is no chemical change: the water molecules remain water molecules. They have simply acquired enough kinetic energy to escape the attraction of the molecules in the liquid and move (almost) freely.
The system remain unchanged.
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
The physical changes that happen in green plants are the changes in appearance. The difference between a sprout and a full grown plant is a physical 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.
A property is an aspect of a sustenance, such as its color, density, (physical properties) and what it will and won't react with (chemical properties). A change is just what it sounds like, something changing. Examples include ice melting, or glass shattering (physical changes) or oxygen reacting with hydrogen to form water (a chemical change).
hi guys ,this is the exact answer according to me,Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties. Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, and density.
hammer+rock+hard impact= quick change physicaly
A fire is a chemical change due to the irreversible changes that happen.
Nothing happens, all stay the same.
