A KEYWORD INTRODUCTION

1. Petrol is a atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood, wood is a atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood and atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood is a gas.

2. Carbon dioxide is a atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood, atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood is a liquid and atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood is a solid.

3a. When atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood are put on the end of a thin wire, it stretches as the atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood are moved further apart.
3b. The forces holding the solid particles together are weakened.

4a. When a syringe is filled with a atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood powder, it is almost impossible to atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood it to a smaller volume.
4b. This is because there is so little atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood between the particles.

5a. It is quite easy to atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood the volume of a gas by compressing it.
5b. This is because there is a atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood of space between the gas particles.

6a. If the air is atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood from a can it collapses.
6b. This is because there are atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood particles atomscompressgasheliumhittingliquidlotmilkmorepumpedreducesolidspaceweightswood the outside of the can than there are hitting the inside surface.
