Electrical Bonding and Kinetic Energy Quick Check 2. Which statement describes the effect of adding more energy to a system, assuming a phase change does not occur?(1 point)

A. The particles within the system will have greater motion, and the temperature will decrease.

B. The particles within the system will have less motion, and the temperature will increase.

C. The particles within the system will have less motion, and the temperature will decrease.

D. The particles within the system will have greater motion, and the temperature will increase

3. Which statement correctly describes how attractions that hold particles break?(1 point)

A. Attractions occur due to gravitational forces. When particles have low enough energy, these forces can no longer keep particles together.

B. Attractions occur due to electrostatic forces. When particles have low enough energy, these forces can no longer keep particles together.

C. Attractions occur due to electrostatic forces. When particles move fast enough, these forces can no longer keep particles together.

D. Attractions occur due to gravitational forces. When particles move fast enough, these forces can no longer keep particles together.

4. Which statement explains why a rubber band analogy is not a perfect comparison for bonds in a substance when considering phase changes?(1 point)

A. For a phase change from solid to liquid, the bonds break completely and particles can move independently of each other.

B. For a phase change from solid to liquid, the bonds do not break completely and particles can still slide past each other.

C. For a phase change from liquid to gas, the bonds do not break completely and particles can still slide past each other.

D. For a phase change from liquid to gas, the bonds break completely and particles can move independently of each other.

5. The boiling point of benzene is 80ºC. Which pair of samples will have the same average kinetic energy as benzene molecules?(1 point)

A. a sample of liquid benzene at 70ºC and a sample of gaseous benzene at 90ºC

B. two samples of liquid benzene, one at 70ºC and the other at 80ºC

C. two samples of gaseous benzene, one at 80ºC and the other at 90ºC

D. a sample of liquid benzene at 80ºC and a sample of gaseous benzene at 80ºC
