(b) An open flask of air is heated, stoppered in the heated condition, and then allowed to cool back to room temperature. Answer the following: 1. Does the flask contain the same, more, or fewer gas molecules now compared to before it was heated? 2. Is the volume occupied by the gas in the flask approximately the same, greater, or less than before it was heated? 3. Is the pressure in the flask the same, greater, or less than before the flask was heated? 4. Do any of the above conditions explain why water rushed into the flask at the lower temperature in the experiment? Explain your answer.
