Select all of the examples of a physical change of state. boiling stirring melting freezing evaporating

Boiling, melting, freezing, and evaporating are all examples of physical changes of state because they involve transitions between different states of matter (solid, liquid, gas) without altering the chemical composition of the substance. For instance, when ice melts, it changes from solid to liquid while still remaining H2O. Stirring, however, is not a change of state; it simply mixes materials together without altering their individual states or compositions. So, while your bubbling pot is changing water from a liquid to a gas, the stirring spoon remains just that—a spoon!
