Which of the following factors determine the state of a substance whether it will be solid, liquid or gas?
Show answer & explanation
Correct answer: A
Explanation
The physical state of a substance (solid, liquid, or gas) is primarily determined by pressure and temperature.
These factors control the kinetic energy of particles and the force of attraction between them, causing the state of matter to change.
Temperature: Higher temperatures increase the kinetic energy of molecules, allowing a substance to change from a solid to a liquid or gas.
Pressure: Higher pressure brings molecules closer together, which helps a gas change from a liquid to a solid.
