Question

it is important to study the ______ of a material to identify the physical conditions or other materials that you should avoid when using this material.

a. attraction

b. absorption

c. reactivity

d. gravity

Explanation:

To solve this, we analyze each option:

• Attraction: Relates to forces drawing objects, not about avoiding conditions/materials.
• Absorption: Involves taking in substances, not about reactions with others.
• Reactivity: Refers to how a material reacts with others/conditions, so studying it helps avoid incompatible ones.
• Gravity: A universal force, not related to material compatibility.

Answer:

c. Reactivity
