SCIENCE IVWrite true if the statement is correct and false if its not.Mixture is a combination of two or more particles.When solid mixed with other solid, it changed its color, size, and shape.Some solid after mixing with other solid can be distinguished from each other.When you mixed solid material with other solid each component does not change at all.Not all solid materials can be distinguished when you mix it with other solid.MATERIALSCan be Distinguished Cannot be Distinguished Sand and pebbles Rice and corn gritsWhite sugar and salt Harina and coffee mate Which combination has distinguishable components?Which mixture looked the same all through out?When two or more materials are combined, a mixture is formed. Solid materials can be mixed/combined with other solid materials. Mixed materials can be classified depending on the appearance of the resulting mixture.When the solid material is mixed with other solid material, each of the combined/mixed materials can be easily identified/distinguished from one another. Such mixture is called heterogeneous mixture.Some solid materials, when mixed with other solids, cannot be distinguished from each other. If the resulting mixture looked the same throughout, such mixture is called homogeneous mixture.The properties of each solid material in the mixture do not change. The size, shape, color of each solid material remain the same even after mixing.

Tell whether the solid mixture is heterogeneous.Rice and corn gritsPowdered coffee and powdered milkSand and pebblesVetsin and fine salt
