The cold war is the political and military tension between democracy and communism. This happened between the United States and the soviet Union. its called the cold war because no weapons were fired.
Ice, water, and water vapor are made of exactly the same type of moleculeâa molecule of two hydrogen atoms and one oxygenatom. What, then, makes them different?Ice, water, and water vapor are different states of water.are the different forms in which matter can exist. The threefamiliar states are solid, liquid, and gas.When a substance changesfrom one state to another, the molecules in the substance do notchange.ce, water, and water vapor are made of exactly the same type of moleculeâa molecule of two hydrogen atoms and one oxygenatom.

168 Unit 2: The Structure of Matter. Solids have a definite volume and shape. A piece of ice,a block of wood,and a ceramic cup are solids.They. have shapes that do not change and volumes that can be measured. Any matter that is a solid has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together.Although the molecules can still vibrate,they cannot move from one part of the solid to another part.As a result,a solid does not easily change its shape or its volume.If you force the molecules apart, you can change the shape and the volume of a solid by breaking it
