Want this question answered?
When a solid melts to become liquid, or a liquid boils to become a gas, the arrangement of particles gets farther apart and less structured, and the motion of the molecules becomes more random and they move faster. The opposite happens when a gas condenses to become a liquid, or when a liquid freezes to become a solid.
As temperature increases in a substance, the component particles become more energetic and eventually a phase change occurs.
The particles are affecting the form of a chemical substance and not turning into a new substance.
They speed up.
proton
The motion slows down, and the arrangement normally packs closer together.
The particles get so attracted to each other making them form into a solid
The particles get attracted to each other, forming a solid.
no the substance is aqueous. oh and its never the particles that are solid/ liquid... they don't really change, its just the molecular arrangement and the intermolecular forces that change
the arrangement of particles in a pancake are that when you prepare the pancake with the ingredients it turns into a liquid and then when you cook it change into a solid
From a liquid to a gas, the particles become more spread out and move slower. From a solid to a liquid, the particles also become more spread out and move slower.
Type your answer here..the shape and volume
When heat is added, the arrangement of the particle (the Entropy of the system) will become more disorganized and Entropy will increase. When heat is taken away, the arrangement of the particles will become more organized and Entropy will decrease.
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. The closeness, arrangement and motion of the particles in a substance change when it changes state.
Freezing is a physical change because the substance that freezes does not change its chemical composition.
