What are the two primary factors that can be varied to change the physical state of matter?
Understand the Problem
The question asks about the two main factors that cause changes in the physical state of matter (solid, liquid, gas, plasma). These factors directly influence the kinetic energy and the intermolecular forces between the molecules or atoms within the substance.
Answer
Temperature and pressure.
The two primary factors that can be varied to change the physical state of matter are temperature and pressure.
Answer for screen readers
The two primary factors that can be varied to change the physical state of matter are temperature and pressure.
More Information
The state of matter (solid, liquid, gas, plasma) depends on the balance between the kinetic energy of the particles (related to temperature) and the inter-particle forces (affected by pressure).
Tips
Many students forget that pressure plays a significant role in the state of matter, focusing solely on temperature.
