Which of the following statements about the gaseous state of matter is not correct? The molecules of a substance is in gaseous state
Answer Details
The statement "have no intermolecular attractive force" is not correct. In the gaseous state, the molecules of a substance are in constant motion, and they have different speeds. The temperature of the gas is an average measure of the kinetic energy of the molecules. However, the molecules in a gas do have intermolecular attractive forces, but these forces are much weaker than in liquids or solids. The pressure of a gas is determined by the number of molecules present and their kinetic energy.
