Physical change, called sublimation. It still stays CO2
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
It is a physical change, as salt (a solid solute) comes out of the solution as the water evaporates.
Yes, a colour change indicates a chemical change.
chemical. when a reaction is undertaken that changes the structure of a substance and creates a new substance it is a chemical reaction. a gas is created during the reaction and a new chemical compound (sodium acetate) is left behind leaving neither of the previous elements present.
there are two changes in matter: physical change and chemical change. physical change means the change in size, shape, texture and any other physical characteristics, but no any new substance made or added. while in chemical change, there's a change in the object's physical appearance but also made a new substance.
its a chemical change
it is a physical change because it is still fruit.
Dissolving sugar in water is a physical change. If you let the water evaporate, the sugar will be left behind. Evaporation is a physical process, not chemical.
both, every chemical change causes a physical change, or the effects would not be apparent or even noticeable.
Chemical change. This is an incomplete combustion, reaction with O2.
Both. In breaking down into humus, both chemical and physical change takes place.
Yes, dissolving sugar in water is a physical change. If you let the water evaporate, you the sugar will be left behind. Evaporation is a physical process, not chemical.-No, It is a Chemical change.
Dissolving sugar in water is a physical change. If you let the water evaporate, the sugar will be left behind. Evaporation is a physical process, not chemical.
As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
chemical change
no because all you are doing is changing the shape and form
because the chemical composition of the nail is changed, forming a new substance (the rust)
