Question

according to the lab guide, which changes below will you look for in order to test the hypothesis? check all that apply. changes in shape or size color changes whether changes are easily reversible temperature changes formation of precipitates or gases changes of state (gas, liquid, or solid)

Explanation:

In a scientific experiment in natural - science (chemistry in particular), these are all common observable changes to test a hypothesis. Changes in shape or size can indicate physical changes. Color changes can be a sign of chemical reactions. Reversibility helps distinguish between physical and chemical changes. Temperature changes often accompany chemical reactions or phase changes. Formation of precipitates or gases is a strong indicator of a chemical reaction. Changes of state are physical changes that can be observed and measured.

Answer:

changes in shape or size, color changes, whether changes are easily reversible, temperature changes, formation of precipitates or gases, changes of state (gas, liquid, or solid)
