During boiling, bubbles appear in the liquid water. in the boxes below represent the

arrangement of molecules inside the liquid water and inside a bubble.

Solids, liquids and gases are the three states of matter.

In solids, the molecules are very tightly packed and they cannot move.

In liquids, the molecules are present close together in a random fashion. They are free enough to move.

In gases, molecules are widely separated.  They can move easily.

The molecules in a liquid can be drawn as:

∅  ∅   ∅  ∅ ∅

∅ ∅  ∅ ∅ ∅∅

∅ ∅ ∅ ∅ ∅ ∅

The molecules in a gas can be drawn as:

∅                        ∅

     ∅

∅                    ∅

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
