Tahle II Determine the Volume of Test Tuhes 1 2 Provide one sample calculation for the volume (cm3) of test tube 1 below: Which method, the measurement of dimensions, or the measurements of volume with a graduated cylinder, do you think gives a better result? Explain. Part II. Volume of Test Tubes using Two Different Methods A test tube's volume can be determined by two different methods. In method one, use a centimeter ruler to measure the inside diameter and the length (or height depending how you hold it) of a test tube to the nearest 0.01cm. When measuring the height of the inside of the test tube, measure to where you think the curvature begins near the bottom of the tube. Do not include the thickness of the glass in the reading. Calculate the volume of each test tube using the formula V =r2h,=3.14,r (the radius) =1/2 the length of a diameter. Round off your final calculation to the appropriate number of significant figures. In method two, measure the volume of the same test tube by filling it with water and pouring the water into a 25mL graduated cylinder. Read the volume on the cylinder by estimating to the nearest 0.1mL. What did you observe about the volume collected via the two different methods? Now repeat this with a different test tube using both methods. If all your test tubes are the same, borrow one of a different size.
