Answer: At a certain temperature the speeds of six gaseous
Chapter 5, Problem 84P(choose chapter or problem)
At a certain temperature the speeds of six gaseous molecules in a container are 2.0 m/s, 2.2 m/s, 2.6 m/s, 2.7 m/s, 3.3 m/s, and 3.5 m/s. Calculate the root-mean-square speed and the average speed of the molecules. These two average values are close to each other, but the root-mean-square value is always the larger of the two. Why?

QUESTION:
At a certain temperature the speeds of six gaseous molecules in a container are 2.0 m/s, 2.2 m/s, 2.6 m/s, 2.7 m/s, 3.3 m/s, and 3.5 m/s. Calculate the root-mean-square speed and the average speed of the molecules. These two average values are close to each other, but the root-mean-square value is always the larger of the two. Why?
ANSWER:Step 1 of 5
Here, we are calculate the root- mean-square speed and the average speed of the molecules.
From the given data,
Speed of six different gaseous molecules are as follows.
= 2.0 m/s , = 2.2 m/s , = 2.6 m/s, = 2.7m/s, = 3.3 m/s and = 3.5 m/s.
