Three samples of three different gases are listed in the table below. All the samples contain exactly 1 mole of gas and are at a temperature of -10.0°C. For each sample, decide whether the gas can be reasonably described as an ideal gas. If the gas isn't ideal, decide the most important reason why it isn't. sample A B C pressure (atm) 1.3 0.72 0.54 volume (L) 20.0 30.0 40.0 ideal? O yes O no O yes O no O O O yes O no If not ideal, the most important reason why not: O There are attractions between the particles. O The particles don't have zero volume. O There are attractions between the particles. O The particles don't have zero volume. O There are attractions between the particles. O The particles don't have zero volume. X Ś
