particles in a substance stay the same whether it is solid, liquid or gas.
solid particles - Have the least energy and is the most dense. They stay the same shape and cant be easily compressed
Liquid particles- They have more energy that solid and only 70% of them are linked together. They are quite dense and cannot be easily compressed.
Gas particles- They have the most energy and are not dense (very low). They can be compressed and they dont keep a definate shape or volume and will expand to fill a container.
