Interpretation : The density of the gas in the window (a) to the density of the gas in the window (b) is to be compared.
Concept Introduction : The connectivity between mass and volume is density. The formula of density is given as:
Answer to Problem 9STP
The density of the gas in the window (a) is lesser than the density of the gas in the window (b).
Explanation of Solution
The connectivity between mass and volume is density. The formula of density is given as:
In the three windows, the volume and temperature are kept constant.
The windows differ in the number of gas particles per unit volume.
The number of gas particles refers to the mass of the gas particle.
The mass of the particle and density are directly proportional to each other.
If the mass increases, the density also increases.
In case of a decrease in mass, the density also decreases.
In the picture, window b has higher gas particles than a and c.
According to the relationship, window (b) will have a higher density than window (a).
