Why doesn't density of a gas depend on temperature?
A) Because the kinetic-molecular theory states that particles are far apart.
B) Because the kinetic energy of a gas system doesn't change with temperature.
C) The density of a gas does depend on temperature.
D) Because the kinetic-molecular theory states that gas particles are extremely small.
Kinetic-Molecular Theory
A theory that explains the properties of gases in terms of the motion of very small particles, considering their collisions as perfectly elastic.
Density
Density is the mass per unit volume of a substance or object, often measured in grams per cubic centimeter or kilograms per cubic meter.
- Elucidate the principles of the kinetic molecular theory and discuss its consequences for the properties of gases.

Final Answer :
C
Explanation :
The density of a gas does indeed depend on temperature. As temperature increases, the kinetic energy of the gas molecules increases, causing them to move apart if the pressure is kept constant, which results in a decrease in density. Conversely, decreasing the temperature would increase the density if the pressure is constant.
