Because monkeys like to eat bananas
Galaxies, earth rotation,
i have no idea im the one thats asking you s*n of a bi*c*
Let it rot. The physical and chemical changes are huge and can be easy shown when you compare a "good" fruit and a rotting version.
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
they are both changes and both are matter
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.
Physical changes are reversible changes, such as change of state (boiling, melting etc), chemical changes are when something undergoes a reaction changing it's chemical makeup.
The particles that make up matter are unchanged during physical, or chemical changes. Matter can neither be created nor destroyed, only transformed.
physicals change is like it changes shapes and other things while chemical change can depend on the color change whether it bubbles or smokes etc.
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
A physical change in contrast to a chemical change is one in which the chemical structure of the compounds involved are left unchanged. Only a physical change occurs. One such example is boiling water. This changes the physical state of water from a liquid to a gas. Similarly, freezing water is a physical reaction. In this case, liquid is frozen to form a solid.
