A clean, dry and open empty flask is being heated in a water bath. Under which conditions before or after heating does the flask contain more gas molecules? Explain.The flask in problem 1 is allowed to cool back to room temperature. Account for the volume occupied by the gas and the number of gas molecules when the gas is cooled to room temperature.Why is it necessary to immerse the flask both in hot and cold water for 5 minutes before taking the temperature?The water levels inside and outside the flask when it was submerged in cold bath must be equal before the flask is removed. Explain.
