<p>The three different states of matter mentioned in the text are gas, liquid, and solid. In solids, particles are tightly held in perfect order, giving them a definite shape and volume. In liquids, particles are close to each other and can move around within the liquid. In gases, particles are far apart and exhibit change in chemical composition.</p> Signup and view all the answers

<p>The main difference between solids and liquids is the arrangement and behavior of their particles. In solids, particles are tightly held in perfect order, giving them a definite shape and volume. In liquids, particles are close to each other and can move around within the liquid, but they do not have a definite shape.</p> Signup and view all the answers

<p>The purpose of measuring properties of matter is to obtain quantitative information. When measuring something, it is compared with a standard quantity that is reproducible and unchanging.</p> Signup and view all the answers

<p>The significance of the particles being far apart in gases is that they exhibit change in chemical composition. This means that gases can easily mix with other substances and undergo chemical reactions. The behavior of gas particles allows for diffusion and expansion to fill the available space.</p> Signup and view all the answers
