Section 1
Gas Density
How does the density of a gas compare with the density of a solid?
Draw a molecular view of carbon dioxide gas.
In your own words, define sublimation and evaporation.
Describe three ways to show that gases exist
When water freezes, the water molecules move apart very slightly. What evidence can you provide to support this claim?
Draw a molecular view for water vapor, liquid water, and ice.
What is the volume of 6.4 $\mathrm{g}$ of $\mathrm{CO}_{2}(s) ?$ (density $=1.56 \mathrm{g} / \mathrm{mL} )$
What is the mass of 3.5 $\mathrm{L}$ of $\mathrm{CO}_{2}(g) ?$ (density $=0.0019 \mathrm{g} / \mathrm{mL} )$
How many grams of $\mathrm{CO}_{2}(s)$ would you need to fill a 6.5 $\mathrm{L}$ bag with $\mathrm{CO}_{2}(g) ?$
A person has 15 $\mathrm{g}$ of dry ice and wants to completely fill a bag that has a volume of 8 L with carbon dioxide gas. Is this enough dry ice to fill the bag with $\mathrm{CO}_{2}(g) ?$ Explain.
