C. Mark "√" in the first column if the sentence What's in describes gases and "X" if it does not portray gases. 1. Gases are hard to compress. 2. Gases expand to fully fill their containers. 3. Gases take the shape of the container wherein particles are able to move naturally to all parts of the container. 4. Particles of gases move at random directions very fast travelling in straight-line paths 5. The molecules of the gas are very large compared to the very short distances between them.
Answer (1)
1. X – Gases are easily compressible, not hard to compress.2. √ – Gases expand to fully fill their containers.3. √ – Gases take the shape of the container, and their particles move freely.4. √ – Gas particles move in random directions at high speeds in straight-line paths.5. X – Gas molecules are very small compared to the distances between them, not large.
