No, mixing cement with water and letting it dry is not a physical change; it is a chemical change. When water is added to cement, a chemical reaction occurs, leading to the hardening and setting of the mixture as it forms new compounds. This process is irreversible, distinguishing it from physical changes, which do not alter the chemical composition of the substances involved.

Is mixing drink into water physical or chemical?
Mixing a drink into water is a physical change because no new substances are formed. The individual components retain their original properties and can be separated again.
Is mixing sugar in water a chemical change or physical change?

Is mixing coffee with hot water a physical change?
no
Mixing a cake a chemical change?
Mixing a cake is a physical change, not a chemical change. In this process, the ingredients physically combine but do not undergo a chemical reaction to form new substances. The mixing can be reversed by separating the ingredients, unlike in a chemical change where new substances are formed.
Is mixing cement a chemical or physical change?
Actually both physical and chemical changes are happening during cement mixing.
Is mixing water and alcohol a physical or chemical change?
Take this as a note. A mixture is always a physical change, as you can simply evaporate the water and have Urea again. Chemical change always involves the changing of reaction properties amongst its reactants.

Is mixing cement and water a irreversible change?
Mixing cement and water is a reversible change because the two substances can be separated by allowing the water to evaporate, leaving the solid cement behind. This process does not alter the chemical composition of either the cement or the water.
