Question

Madame puts a teabag in her mug of water. Before she has a chance to stir the tea, she hears a sound and goes to see what it was. When she comes back, the tea is distributed throughout the mug. It looks like someone stirred it, but no one else is home. What happened?

Answer 1

See the answer below

Step-by-step explanation:

What really happened was that the component molecule present in the teabag became hydrated as a result of dissolution in water. Once dissolved, the molecules start to move about from the region of higher concentration - that is, the tea bag - to the region of lower concentration until the molecules become uniformly diffused throughout the water in the mug.
