According to the kinetic molecular theory, which property of gases is primarily driven by the kinetic energy of the molecules?

• A. Density of the gas
• B. Solubility of the gas in water
• C. Color of the gas
• D. Pressure exerted by the gas

Answer: (D)

Verified step by step guidance

1. Recall that the kinetic molecular theory explains the behavior of gases based on the motion of their molecules.
2. Understand that the kinetic energy of gas molecules is directly related to their speed and motion.
3. Recognize that pressure in a gas arises from collisions of gas molecules with the walls of their container.
4. Connect that the frequency and force of these collisions depend on the kinetic energy of the molecules.
5. Conclude that among the given properties, the pressure exerted by the gas is primarily driven by the kinetic energy of its molecules.
