State whether the statement is true or false. According to the kinetic molecular theory, the collision between gas molecules is perfectly elastic.

Answer

To determine whether the statement "According to the kinetic molecular theory, the collision between gas molecules is perfectly elastic" is true or false, we can follow these steps:

### Step 1: Understand the Kinetic Molecular Theory (KMT)
The Kinetic Molecular Theory explains the behavior of gases in terms of particles in motion. It states that gas molecules are in constant, random motion and that they collide with each other and with the walls of their container.

**Hint:** Recall that KMT describes the behavior of gas molecules and their interactions.

### Step 2: Define Elastic Collisions
An elastic collision is one in which there is no net loss of kinetic energy in the system as a result of the collision. This means that the total kinetic energy of the colliding molecules before and after the collision remains the same.

**Hint:** Remember that in elastic collisions, kinetic energy is conserved.

### Step 3: Analyze Collisions According to KMT
According to the Kinetic Molecular Theory, when gas molecules collide, they do so without any loss of kinetic energy, which means that these collisions are perfectly elastic. The molecules may change direction after the collision, but their speed (and hence kinetic energy) remains unchanged.

**Hint:** Think about how gas molecules behave in a container and how they interact during collisions.

### Step 4: Conclusion
Since the Kinetic Molecular Theory states that the collisions between gas molecules are perfectly elastic, we can conclude that the statement is true.

**Final Answer:** The statement is **True**.
