2. 15. Most collisions in everyday world are a. elastic collision c. perfectly elastic collision b. inelastic collision d. perfectly inelastic collision
Answer:
A. Inelastic Collision
Explanation:
is perfectly inelastic because the maximum possible kinetic energy has been lost. This doesn't mean that the final kinetic energy is necessarily zero momentum must still be conserved3. Two cars collide, lock bumpers, and move together after the collision. What kind of collision is this? A. Elastic collision B. Inelastic collision C. Perfectly elastic collision D. Perfectly inelastic collision
inelastic collision
Explanation:
This is an example of an inelastic collision, as the two cars stick together after colliding.

7. which of the following is conserved in an elastic collision but not in an inelastic collision? A. Force B. Momentum C. Acceleration D. Kinetic Energy
Answer:
B
Explanation:
Momentum is conserved in inelastic collisions, but one cannot track the kinetic energy through the collision since some of it is converted to other forms of energy.
8. What will happen to the reaction system if there is an increase in temperature? a. More collisions occur, but the collision energy is the same. b. More collisions will occur, resulting in a higher reaction rate. c. The same number of collisions occurs with the same collision energy. d. The same number of collisions occur but with greater collision energy.
Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).9. the rate of a reaction depend onA. Collision frequency B. collision energy C.collision orientation D. all of the above
Answer:
D. all of the above
Explanation:
The rate of a reaction depends on collision frequency, collision energy and collision orientation.
