Question

Which of the following statements is true about gas particles?

a. They repel each other with a strong force.
b. There is a lot of empty space between them.
c. They collide to increase their net kinetic energy.
d. There is a strong force of attraction between them.

Answer 1

The true statement about gas particles is that there is a lot of empty space between them. This reflects the properties of gases as defined by the kinetic-molecular theory, where gas particles are in constant, rapid motion and interact with each other through elastic collisions without forces of attraction or repulsion.

Step-by-step explanation:

The statement that is true about gas particles is: b. There is a lot of empty space between them. This is based on the kinetic-molecular theory, which describes the behavior of gases in terms of motion and particle interactions. According to this theory:

• Gases consist of tiny particles that are far apart from one another, with the distance between them being much greater than their size.
• Gas particles move in constant, rapid, and random motion, resulting in elastic collisions where there is no net loss of energy.
• There are no forces of attraction or repulsion between gas particles, indicating that their interaction is negligible.
• The average kinetic energy of the gas particles is dependent on the temperature of the gas, meaning as the temperature increases, so does the kinetic energy of the particles.
