Which examples best demonstrate the benefit of understanding physical properties?
select all that apply.
*scientists can predict how well two substances will react.
*engineers can design better bridges because they know how metal changes shape.
*engineers can design safer structures because they understand the flammability of building materials.
*scientists can easily classify mixtures of unknown substances.

*Engineers can design better bridges because they know how metal changes shape.

*Scientists can easily classify mixtures of unknown substances.

Explanation:

Tensile strength and the properties of mixtures are physical properties because the substances are not changed into different ones.

A. and C. are wrong. Combustion and other reactions are chemical properties because the substances are changed into different ones

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
