According to the kinetic molecular theory, which condition must a gas satisfy for Boyle's and Charles' laws to be applicable?

• A. The gas must behave ideally, with negligible intermolecular forces and particle volume.
• B. The gas must consist of polar molecules.
• C. The gas must undergo chemical reactions during compression or expansion.
• D. The gas must be at very high pressure and low temperature.

Answer: (A)

Verified step by step guidance

1. Recall that Boyle's law and Charles' law describe ideal gas behavior, which assumes certain conditions about the gas particles.
2. Understand that the kinetic molecular theory models gases as particles in constant, random motion with negligible volume and no intermolecular forces.
3. Recognize that for Boyle's and Charles' laws to apply accurately, the gas must behave ideally, meaning the particles do not attract or repel each other and their own volume is insignificant compared to the container volume.
4. Note that gases consisting of polar molecules or undergoing chemical reactions do not behave ideally, so these conditions violate the assumptions of the kinetic molecular theory.
5. Also, very high pressure and low temperature cause gases to deviate from ideal behavior because particle volume and intermolecular forces become significant under these conditions.
