I recently posted a question What will be the final temperature in this case? Which contained information about a thermodynamical process and asked to calculate work done. The question was tagged "homework type" and then closed.
I deleted that one and asked again in a different version from different account. But it was closed too. Why are these people closing these questions? This type of question helps me and others clear concepts. Which concept I missed in the particular question and there could be other approaches for that question that gives new ideas.
The Mathematics and Chemistry Stack Exchange sites don't do these types of silly things. Why do PSE does it?
