by raw materials that changes materials
no because they arent chemically combined
Yes, materials do change when physical properties are measured.
it is chemical change
Materials lose their original properties when their spatial conditions change, provided their atomic configuration change.
YES
A chemical change occurs when new substances are formed with different properties, such as rusting of iron or baking a cake. A physical change involves a rearrangement of molecules without forming new substances, like dissolving sugar in water or melting ice.
No
No. Making mixtures are physical changes and the chemical substances will not change.
Mixtures are combinations of two or more pure substances that retain their individual properties and can be separated by physical means. Unlike pure substances, which have a uniform composition and distinct properties, mixtures can vary in composition and may exhibit different characteristics depending on the proportions of the components. Examples of mixtures include air, saltwater, and salad, where each component remains identifiable and does not chemically change.
No, light does not cause the same change to all materials. Different materials react differently to light, depending on their properties and composition.
umm....CHEMICAL change..! 0.o
A mixture is the combination of two or more materials where the properties of the individual materials remain unchanged. Each component retains its original characteristics and can be separated back out.
