Fundamentals of matter in physical science: In basic physics and chemistry, matter can exist in which principal states under ordinary conditions?

Introduction / Context:
This question checks core understanding of how matter presents itself in everyday physical science. Recognizing the common states establishes a foundation for later topics such as phase change, thermodynamics, and materials engineering.

Given Data / Assumptions:

• The focus is on principal states encountered in school science and general engineering.
• Extreme or exotic states like plasma or Bose–Einstein condensate are beyond the basic scope unless specifically asked.

Concept / Approach:
Matter typically exists as solid, liquid, or gas depending on temperature and pressure. In solids, particles are closely packed with fixed shape and volume; in liquids, particles are close but can flow with fixed volume and variable shape; in gases, particles are far apart with neither fixed shape nor fixed volume.

Step-by-Step Solution:
Identify the three principal states commonly taught: solid, liquid, gas.Scan the options for this exact trio in any order.Select the choice that lists solid, gas, or liquid together.

Verification / Alternative check:
If a substance is heated or cooled at standard pressure, it transitions among these three states via melting, freezing, vaporization, condensation, and sublimation; this confirms the three principal states.

Why Other Options Are Wrong:

• Solid, liquid, or mineral: mineral is a material category, not a state of matter.
• Mineral, gas, or liquid: same issue; mineral is not a state.
• Plastic, solid, or gas: plastic is a class of polymers, not a thermodynamic state.
• Plasma, condensate, or crystal only: plasma and condensate are exotic states; crystal refers to structure within a solid, not a separate state.

Common Pitfalls:
Confusing material classes (metals, plastics, minerals) with physical states; mixing structure descriptors like crystalline or amorphous with states.

Final Answer:
solid, gas, or liquid
