Explanation:They teach us two experiments about solids,liquids and gas.The first experiment they put ice cubes(solid) in a plastic bag(solid)and melt it into water(liquid).After that,they put tablets in the plastic of water to make gas and make the plastic full of pressure and make the plastic blow.The second experiment ,they melt an ice cube with salt because salt makes ice melt faster.So the conclusion of the first experiment is :they melt the ice and the ice turns into water and put some tablets to make gas.
The conclusion of the second experiment is: They try to show us that if we put salt when we want to melt an ice it makes the ice melt faster.
explanation :They teach about , gas well separated with no regular arrangement, liquid are close together but solid are tightly packed,usually in a regular pattern.
