Question

According to the kinetic molecular theory, which of these statements is NOT true?

A. There is no attraction between particles of a gas.
B. Only particles of matter in the gaseous state are in constant motion.
C. The particles of a gas collide with each other and with other objects.
D. Most of the volume of a gas is just empty space.

Answer 1

B; false, all forms are slightly moving or vibrating, even solids

Answer 2

The statements B. is NOT true.

Step-by-step explanation:

Option A. is true because there are no interactive forces (attraction or repulsion) between the particles of a gas, they are constantly colliding with each other and the walls of their container but without interacting with each other.

Option B. is false because even solids are constantly moving, even though the particles that form them are joined by large attractive forces so that they occupy almost fixed positions and can only move vibrating or oscillating around fixed positions.

Option C. is true because the kinetic model is a theory based on different gas characteristics: the gas is composed of a large number of molecules moving in random directions and frequently collide with each other and with the walls of any container.

Option D. is true because being the gas particles weakly attached, they occupy the entire volume of the container that contains it and most of the volume of a gas is just empty space.
