Physical change - a change in a substance that does not involve a change in the identity, including a change in state between solid, liquid and gas phases.
Chemical change - a change which one or more substances are converted into different substances, some indications are burning, rusting, color changes etc.
physical change can be changed
but in chemical change chemicals are mixed together
for example if we are sick that is a physical change
we have to change healthy as well
when we mix salt in a dish,can we take out that again?
never
this is chemical change
A physical change is when the object undergoes a change that can be reversed, such as mixing water with salt, melting ice, or freezing or vaporizing water. A chemical change is a change that changes a substance into something else entirely, and therefore cannot be reversed. Examples would be mixing vinegar and baking soda or turning batter into bread.
chemical change is when during a chemical reaction a new substance will be formed while in physical change no new substances are formed
A chemical change is a change in which a substance turns into a completely different substance that can't be reversed. A chemical change often happens when asubstance burns (not to be confused with evaporation or melting of a substance), changes colors, a substance spoils or rusts, photosynthesis or respiration, and/or a substance tarnishes. Some examples are a bike rusting, burning bread to make toast, fireworks exploding, milk spoiling, a leaf changing color, mixing eggs and flour for a batter, baking a cake, etc.
A physical will dissolve, go through a state of matter (sublimation, decomposition, melting, freezing, evaporation, and condensation), break or tear a substance, and/or anything that can be reversed back. This could be glass breaking, salt dissolving in water, ice melting, water evaporating, paper tearing, sugar dissolving in tea, etc.
a chemical change has properties like tarnishing,rusting , burning,and photosyntesis also there is always a reaction and something new and a phsical change has properties like odor, taste,and texture theres no reaction or something new
It is a physical change.
chemical change
Physical change
Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
Drying (involving only the water evaporation) is a physical change.
Chemical broooooooooooooooo niga
it is a chemical change
Chemical I think
physical as the chemical structure does not change.
A physical change
Physical - there are no chemicals involved

It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
Physical change of the paint, not the door.
Melting is a physical change.
