Does the size of the room matter?

anonymous · Answer

I don't think so.

So, you're telling me that the air in your living room weighs as much as the air in the Mall of America.  Really?

anonymous · Answer

? Im confused. No I wasn't talking about my room. This is a physics problem from my homework assignment that I needed help on.

Why did we start over?

You said, "What is the weight of the air in the room?"

I wondered, "What room?"  The went straight to me question, "Does the size of the room matter?"

You answered, "I don't think so." - Not exactly filling me with confidence.  Thus, I thought to challenge your premise with what I thought would be a ridiculous comparison - Living Room vs. Mall of America.

Thus, here we are, back to, "Does the size of the room matter?"  Either it does or it doesn't.

yes the size does matter

Well, then we're going to have to know something about the room, no?
