Chemical Equilibrium - Analogy

The video tutorial explains the concept of dynamic equilibrium using a seesaw as an example. It describes how a seesaw behaves when a person and a child sit on it, and how it stabilizes when two children of similar weight are on it, leading to a state of dynamic equilibrium. The tutorial also provides real-life examples of dynamic equilibrium, such as a man on an escalator moving in the opposite direction and a man running on a treadmill.

What causes the seesaw to tilt towards the person when a person and a child are sitting on it?

• The seesaw is unevenly balanced.

• The person has greater weight than the child.

• The child is heavier than the person.

• The person is sitting closer to the center.

When two children of nearly equal weight sit on a seesaw, what eventually happens?

• The seesaw stabilizes and does not move.

• The seesaw breaks due to weight.

• The seesaw tilts towards one child.

• The seesaw remains in constant motion.

What is the term used to describe the state when two children on a seesaw are balanced and not moving?

• Linear equilibrium

• Rotational equilibrium

• Dynamic equilibrium

• Static equilibrium

Which of the following is an example of dynamic equilibrium?

• A car parked on a hill

• A pendulum at rest

• A man running on a treadmill

• A book resting on a table

In the context of dynamic equilibrium, what is happening when a man goes up an escalator that is moving downward?

• The man is in dynamic equilibrium.

• The man and the escalator are moving at the same speed.

• The man is in a state of rest.

• The man is moving faster than the escalator.
