PART TWO: CALCULATING THE VOLUME AND WEIGHT OF THE AIR IN A ROOM Data 1. Measure and record the length and width of a room that has a flat ceiling at three different locations. Estimate the ceiling height of the room without actually measuring it. 2. Make a guess of the weight of the air in the room and record your guess.

3. Find, using your textbook or an internet search, the density of air in units of kilograms per cubic meter. 4. Create the data table and enter your measurements. Calculations 1. Calculate the volume of the room in cubic meters. 2. Determine the best estimate of the error of this measurement. 3. Convert the density of the air you found in kilograms per cubic meter to Newtons per cubic meter by multiplying by "g", the acceleration due to gravity, i.e., 9.8 m/s^2. The density of air in kilograms per cubic meter is called a mass density because it is mass divided by volume. The density of air in Newtons per cubic meter is called a weight density because it is weight divided by volume. 4. Calculate the weight of air in the room in Newtons by multiplying the weight density of air you calculated in #3 (in Newtons per cubic meter) by the volume of air (in cubic meters) you calculated in #1. 5. Determine the best estimate of the error of this measurement and record the value on the data table. 6. Convert the weight of air in the room that you calculated in #4 from Newtons to pounds and record your result. Does the weight of the air in the room (in pounds) surprise you?
