Question

Rank the samples of gas descibed in the table below in order of increasing average speed of the atoms or molecules in them. That is,select t' next to the sample in which the atoms or molecules have the slowest average speed. Select "2 next to the sample in which molecules have the next slowest average speed, and so on. average speed of atoms or molecules gas sample 2.3 mol of neon gas at 1.9 atm and -5. °C 2.4 mol of krypton gas at 1 8 atm and-5-c 1.7mol of neon gas at 2 8 atm and 73 1.6 mol of neon gas at 2.0 ats and 34 C Choose one) [Choose-one)g (Choose one) Choose one) |

Explanation / Answer

The average speed of atoms and molecules depend on the size of molecules and the temperature and pressure conditions. The speed is higher at the higher temperatures and lower at lower temperatures.

So here :

2.3 mol of neon gas at 1.9 atm and -5o C : 3

2.4 mol of krypton gas at 1.8 atm and -50 C : 4

1.7 mol of neon gas at 2.8 atm and 73o C : 1

1.6 mol of neon gas at 2.0 atm and 34o C : 2
