Is cornflour and water a physical change?
Adding cornflour to water is a physical change. The reason this process is classified as such is that it does not change the chemical identities of the substances involved, which is the criterion for a process to be considered a chemical reaction. Technically, the cornflour would slowly hydrolyze in water, which would be a chemical reaction.
Is adding sand and water a physical change or a chemical reaction?
