What Are Their Main Differences?
The key difference between 'what' and 'why' depends on the information given to each question or in other words, the difference relies on the answers they seek for. Actually, 'why' asks for an explanation or reason for something. 'What' is used to ask questions about things and actions.

a nice day!")

What They Require as an Answer?
Actually, the term 'what' is concerned with the question about things and actions.
The term 'why' is concerned with the question of 'for what'.
Making Questions by These Interrogative Pronouns
Since the term 'why' asks for the reason of something there is not any other way but its usual way to make questions. By the usual way, we mean to put the interrogative 'why' at the beginning of a sentence and then make a yes/no question that follows it. This method also works for questions with 'what', unless we are questioning the subject of a sentence. In this case, you should put the interrogative pronoun 'what' instead of the subject and put a question mark at the end.
Here in this example, the answer can be the spoiled meat smells bad in this kitchen. Since the answer is the subject of the sentence, to ask questions all you have to do is to put the wh-word instead of the "spoiled meat".
