The document discusses three states of matter - solid, liquid, and gas - represented by diagrams A, B, and C. Diagram A represents a solid that cannot be compressed, while diagram C represents a gas that can be compressed. Diagram B represents a liquid like water. The document also provides a condensation equation showing a gas (C) changing into a liquid (B) through condensation.

The three states of matter are represented in the diagrams below.
A B C
a) Identify the diagram that represents
i) A solid. A
ii) Steam. C
b) Name a substance that could be represented by diagram B. Water
c) Explain why substances represented by diagram C can be compressed, but the
others cannot.
Because C is Gas, so the other must be solid and liquid. Solid can’t compress because
the particle stay together, can’t move. Liquid can’t compress because the particle stay
touching together, so it can for some liquid but also can’t for some.
d) Condensation is a change of state. Complete the condensation equation below by
putting one letter from the diagrams above (A, B, C) into each circle.
