Blog your learning-Investigating matter

Matter is a physical substance which has mass and volume. If you want to remember the states and there changes think water. Vapour is gas, water is liquid, and ice is solid. Now if you want to know how to change a solid into a liquid how would you turn a ice cube into water. You add heat; melting. If you want to change a solid into a gas how would you change an ice cube into vapour, by adding even more heat; sublimation. A gas into a solid or vapour into and ice cube you do the opposite, reversing sublimation; disposition. You have vapour and want to turn it into water, a gas to a liquid; condensation. Now you want to do the opposite turn a liquid into a gas you want evaporation. And finally a liquid into a solid, taking water and tuning it into an ice cube; Freezing. Kinetic molecular theory is the theory of how particles move. The movement can differ depending on the amount of energy coming from certain states. From the bag of change lab i learned that even the most basic day to day items can be mixed together and cause chemical changes. Some times chemical reactions cant just be seen but they can also be changed in a variety of different ways.
