Determine whether the following are physical or chemical changes:
A new solid forms in a solution.
Chemical changes are those in which a new chemical compound is formed. The word "new" means to me a different solid so I would go with chemical change for this.
Physical changes are those in which the initial substance is not changed. Changes in temperature, color, size, shape-----those are physical changes.
thankyou!
To determine whether the formation of a new solid in a solution is a physical or chemical change, you can think about the definition of each type of change.
A physical change is a change that does not result in the formation of a new substance. It only affects the physical properties of the substance, such as its shape, size, or phase. In contrast, a chemical change is a change that results in the formation of one or more new substances with different chemical properties.
In the given scenario, the formation of a new solid in a solution suggests that a chemical change is occurring because a new substance is being formed. When certain substances dissolve in a solvent, they can react with one another to produce a new solid. This process is known as precipitation.
Therefore, in this case, the formation of a new solid in a solution represents a chemical change.
