5. If the pressure exerted on a gas in a flexible container is increased does the density of the gas
change? Why or why not? Explain your answer

 Yes, the density of the gas will change.

Density can be described as mass per unit volume.

The greater the pressure, the greater will be the density as there will be more volume of the gas particles in a pressurized state.

A decrease in pressure will cause the density to decrease.

The density does change.

Explanation:

Density is given by mass per volume.;

D = M / V

While the mass of the gas is not changing, the volume of the gas is changing based on the pressure applied to the gas. If the volume increases, then the density of the gas decreases (because of mass decreases per volume). If the volume decreases then the density increases (because mass per volume increases).
