What changes take place when a substance goes through a phase change?
During a phase change, the arrangement of the particles changes while the chemical composition remains the same. Energy is absorbed or released, causing changes in temperature and state. Phase changes include processes like melting, freezing, vaporization, condensation, and sublimation.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
