It is a physical change. When the water vapour inside of the freezer turns to frost (ice), it hasnt changed the fact that it is still water, just in a different form. Therefore, this is a physical change.
Cracking an egg is a physical change, not a chemical change.
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
Chemical. The chemical composition of the egg is changed when the egg is fryed, and cannot be reversed.
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
When something is alive, there are chemical reactions going on constantly within it. The technical definition of being deadis that of chemical equilibrium. When a system (for example, a beaker with chemicals inside it, or an animal) is in chemical equilibrium, there is no reaction that can take place without an input of energy. Since an animal in chemical equilibrim cannot do anything, it is considered completely dead.So, in short, dying (that is, ceasing to be alive) is nota chemical change. Instead, dying is a lack of chemical change.
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
physical change since the egg and the contents inside do not become a new substance they remain the same only thing is that the shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because its internal composition is the same
Cracking an egg is a physical change, not a chemical change.
The egg actually turns solid inside, so that is a physical change. If the egg turned into a liquid or gas after boiling it then that would be considered "chemical change"
Discharging a battery involves a chemical change where the stored chemical energy is converted into electrical energy. This is not considered a physical change because the composition of the materials inside the battery changes during the discharging process.
Blowing up a balloon is a physical change because the air being blown into the balloon does not alter the chemical composition of the balloon material. The change is reversible, as the balloon can be deflated and reinflated multiple times without changing its chemical makeup.
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
The air inside the balloon will contract, so the balloon will tend to look slightly crinkled.
chemical change,because the liquid form inside the ice candy plastic,changed into a solid particles and getting iced.
In a physical change, the chemical composition of the substance does not change, it merely changes form. In a chemical change, the chemical formula changes so that fundamental properties such as density and molar mass change.
Chemical. The chemical composition of the egg is changed when the egg is fryed, and cannot be reversed.
