Which of the following causes a change in the state of matter?
Changing temperature or pressure
The physical state of matter (solid, liquid or gas) depends on how strongly its particles are held together and how much kinetic energy they have. Changing the temperature or pressure changes this balance: heating gives particles more energy so a solid melts and a liquid boils, while increasing pressure pushes particles closer and can liquefy a gas. This is why temperature and pressure are the factors that cause a change of state.
Cutting a substance only divides it into smaller pieces; each piece stays in the same state. Mixing it with another substance or dissolving it produces a mixture or solution but does not, by itself, change the physical state of the original matter. These are physical changes of form or composition, not changes of state.
Hence, the answer is changing temperature or pressure.
