Create a table that describes the three common states of matter in terms of their shape, volume, and compressibility.

Solid: Volume = Definite Shape = Definite Compressibility = Incompressible Liquid: Volume = Definite Shape = Takes shape of container and fills container to the extent of its own volume Compressibility = Virtually incompressible Gas: Volume = Fills volume of container Shape = Takes shape of container Compressibility = Compressible

Explain why the flow of a compressed gas must be controlled for practical and safe use.

The flow of compressed gas must be controlled to control the amount and the rate at which gas is released.

Describe the characteristics that identify a sample of matter as being a substance.

The sample of matter must have a uniform and unchanging composition to be a substance.

Predict what would happen if the valve on a full tank of compressed gas were suddenly opened all the way or if the tank were accidentally punctured.

Without the regulator device, the gas would rush out of the tank with a force powerful enough to transform the tank into a dangerous, uncontrolled projectile.

Classify each of the following as a physical or chemical property.

a. chemical b. physical c. chemical d. physical e. physical
