The document contains diagrams representing the three states of matter - solid (A), liquid (B), and gas (C). It asks students to (1) identify which diagram represents a solid and gas, (2) name a substance that could be a liquid, and (3) explain why gas can be compressed but solids and liquids cannot. It also has students complete a condensation equation using the diagram letters.

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. _ Liquid_______
c) Explain why substances represented by diagram C can be compressed, but the others
cannot.
Because the circles shown in the other boxes are already too close together to be.
compressed again.

2. d) Condensation is a change of state. Complete the condensation equation below by putting
