'Sand is mixed with salt' is a physical change because it involves a combination of two substances without altering their chemical identities. The individual particles of sand and salt retain their properties and can be separated by physical means, such as dissolving the salt in water or using filtration. No new substances are formed during this process, which is a key characteristic of physical changes.
