What is matter?<|im_end|>
<|im_start|>assistant
Matter is anything that takes up space and has weight. It's all around us and can be found in many different forms, like solids, liquids, and gases.<|im_end|>

Can matter change?<|im_end|>
<|im_start|>assistant
Yes, matter can change. For example, ice (a solid) can melt into water (a liquid), and water can evaporate into steam (a gas). These changes are called physical changes.<|im_end|>

Is that the same as a chemical change?<|im_end|>
<|im_start|>assistant
No, a chemical change is different. It's when matter changes into a completely new substance, like when wood burns and turns into ash. In a chemical change, the matter can't be easily changed back into its original form.<|im_end|>
