Final answer:
Substances can be consumed or interacted with as solids, liquids, gases, or other forms such as vapors and solutions, which affect how they enter the body and their potential effects. (option a)
Step-by-step explanation:
A substance can typically be consumed or interacted with in various forms, and the state it is in greatly affects how it enters the body and the potential harm it can cause. Chemical substances commonly exist as solids, liquids, or gases. Each of these states has different properties, such as intermolecular forces and energy states, which determine their physical behavior and interaction with the environment. For instance, substances with relatively strong intermolecular forces and high melting points that are not easily compressed are generally solids.
Regarding consumption, especially in the context of drugs, a substance can be inhaled, injected, smoked, ingested, absorbed via the skin through patches, used as a suppository, or dissolved under the tongue. These different methods of consumption reflect the various forms a substance can take, including vapors, mists, or solutions, and the different pathways they can enter the body.
Hence, the answer is option a
