Question

What causes changes in the states of matter?

Answer 1

Answer: Energy

Explanation: If you take a solid ice cube and when you put it under the sun it melts and becomes a water which is a liquid. And if that liquid evaporates it becomes a gas. Hope that helps :)

Answer 2

Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matter’s chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. Energy is always involved in changes of state. Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings. The amount of energy in matter can be measured with a thermometer. That’s because a thermometer measures temperature, and temperature is the average kinetic energy of the particles of matter.

Step-by-step explanation:

So the answer is energy.
