question select all the correct answers. which observations show that a change in state of matter has occurred? wood burns, producing gas and an ashy residue. overnight, dew forms on the grass. an alkali indicator changes color when added to a cleaner. vinegar has a strong smell.

Answer

Brief Explanations:

A change in state of matter involves a physical change from one state (solid, liquid, gas) to another. Wood burning is a chemical change. An indicator color - change is a chemical reaction. Vinegar's smell is a property, not a state - change. Dew forming on grass is water vapor (gas) changing to liquid water, which is a change in state of matter.

Answer:

Overnight, dew forms on the grass.
