How do people's choices affect how matter is used?
Matter is composed of atoms, molecules and other particles. People's choices affect how matter is used because the actions can change the state. For example, heating ice changes it from the solid state to liquid state.
Um... what? Matter is everything. Like molecules and fire hydrants and horses and meteors. Choices don't really affect how matter is used aside from choosing what is going to be made...
I think the question is a bit unclear.I think the answer would be say I freeze water, I just changed matter (liquid to solid)
