The States of Matter Solid Liquid and Gas

Hello, am Jared. Welcome to funsciencedemonstrations for young learners. The big idea today is that there are three states of matter. There are solids there are liquids and there are gases. can not show you the gasses because they are clear. Well, science tells us the gases in this room, in our atmosphere are largely made up of two gases: about 20% oxygen - and that oxygen is really important to us as humans - and the rest 80% roughly, 75% is nitrogen. The nitrogen is really important to plants. It is beneficial. They are cool, but they are clear, we can not see them, and we want to talk about them. So how do we do it? Well, we are going to create gas, and hopefully get you to see it, using science. So, have two substances, two materials. To make that happen, we have baking soda and we have vinegar. These two ingredients will create another gas. You can not smell it through the video camera, but you will be able to see it, la" the candle. So, here we go. We are going to dump in the baking soda, and when add the vinegar should get reaction. How do tell? It is reaction that is going to bubble. It is going to foam. It is not going to pop up like volcano, but you are going to see the fizz happen almost like soda. gas is given off. What do you think is coming out of those bubbles? Well, it is actually carbon dioxide. Carbon dioxide is not oxygen, carbon dioxide should be able to extinguish and put out this flame. It is actually lot heavier than the air around us, so it should stay in the beaker. It is not going to be spilling over the sides. You could not see it, it will stay in the beaker, and am going to prove it to you. Now, for the science! We add that, we add the vinegar, now for the science, we add the vinegar - you can see the reaction, the foaming action, the bubbling, the popping... plop, plop, fizz, fizz, there is gas is being released in that beaker but you can not see it. Neither can It is in there. It is heavy, so should be able to actually pour the gas on to the flame and watch the flame go out this is the cool part I'm not gonna pour any of the liquid I'm gonna pour the gas out of here on to the flame well did not blow that candle out. The carbon-dioxide smothered it. It is like putting an invisible blanket on the flame. Oxygen can not get to it. All the carbon dioxide swirls around that flame. The candle can not take any of the oxygen in the air, the carbon dioxide put out the flame. Science is so cool! Thanks for watching.
