What is the difference between the two sentences?

Question

1. The food gets cooked.

2. The food is cooked.

I get to hear both of the sentences. Are they same or different. Please explain, Sir.

Answer 1

The food gets cooked.

Cooking is what happens to the food.

For example:

At the cafeteria, rice gets cooked in large vats.

Whereas with is:

The food is cooked.

the meaning can be the same:

At the cafeteria, rice is cooked in large vats.

or it can be different:

This fish is cooked.

The fish is not raw. A cook prepared it in some way: frying, baking, broiling, steaming, smoking, etc.
