Question
Four samples of the same unknown gas G are listed in the table below. Rank these samples in increasing order of ideality. That is, select 1 next to the sample of G that will behave least like an ideal gas, and select 4 next to the sample of G that will behave most like an ideal gas.sample pressure volume temperature How ideal the sample is:atm L °CA 30.0 2.0 −25.0 ▼2B 35.0 3.0 −25.0 ▼3C 30.0 3.0 −10.0 ▼1 (least ideal)D 25.0 1.0 −10.0 ▼4 (most ideal)
Solution
The ideal gas law states that PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. According to this law, a gas behaves most ideally at low pressures, high volumes, and high temperatures.
Looking at the table, we can rank the samples as follows:
-
Sample C: This sample has a relatively high pressure (30.0 atm), a high volume (3.0 L), and a relatively high temperature (-10.0 °C). This makes it the least ideal gas sample.
-
Sample A: This sample has a relatively high pressure (30.0 atm), a low volume (2.0 L), and a low temperature (-25.0 °C). This makes it slightly more ideal than sample C, but less ideal than samples B and D.
-
Sample B: This sample has the highest pressure (35.0 atm), a high volume (3.0 L), and a low temperature (-25.0 °C). This makes it more ideal than samples A and C, but less ideal than sample D.
-
Sample D: This sample has the lowest pressure (25.0 atm), the lowest volume (1.0 L), and a relatively high temperature (-10.0 °C). This makes it the most ideal gas sample.
