Questions & Step-by-Step Solutions
In the kinetic theory of gases, the term 'elastic collision' means: (2019)
Step 1: Understand what a collision is. A collision happens when two objects hit each other.
Step 2: Learn about elastic collisions. In an elastic collision, the objects bounce off each other without losing energy.
Step 3: Know that kinetic energy is the energy of motion. In elastic collisions, the total kinetic energy before and after the collision stays the same.
Step 4: Understand momentum. Momentum is the quantity of motion an object has, and it is also conserved in elastic collisions.
Step 5: Remember that in the kinetic theory of gases, we assume that gas particles collide elastically, meaning both kinetic energy and momentum are conserved.
