Matter cannot be created or destroyed, but can change from one state to the other with the application or removal of heat (temperature). Each time matter changes state, it is simply the movement of molecules in them speeding up or slowing down. For example:Let us use water as an example. At room temperature, water is . . .
The particles in solids, liquids and gases all behave in different ways but result in a similar way. They all expand when heated up. Solids: The particles in solids vibrate more and knock against each other when heated and result in taking up more space. The property of solids (metal) expansion makes it possible to join two metal pieces withou . . .
All three states result in taking up more room, also know as expansion. The expansion properties of solids, liquids and gases have some advantages and disadvantages. One advantage of expanding metal is its use in thermometers. The mercury (liquid-metal) in the tube expands when they get hotter. One disadvantage of expansio . . .
