Start Calculating Volume. Now we need to move on to calculate volume and how we handle propagating the uncertainties from our radii and heights into an uncertainty for the volume. For the rest of the lab, work in centimeters (if you are not already).
To determine the internal diameter and depth of a cylinderical container (like tin can, calorimeter) using a vernier callipers and find its capacity. Verify the
Maximum value of λ is obtained with maximum value of d and maximum value of θ. λmax = (1 + 0.05)x10−6xsin(30 + 0.5) = 0.53m. λmin = (1 − 0.05)x10−6xsin(30 − 0.5) = 0.47m. λ = 0.50 ± 0.03m. Note: The same method may be used for any uncertainty calculation e.g. Density = mass/volume.
Theory. Using the proper instrument is extremely important for making accurate measurements of physical properties. The easiest way to measure length is to use a meter (or English yard) stick. For normal everyday measurements, a visible comparison between the object of interest and the scale is all that is needed.
Volume in physics refers to the amount of space occupied by a body or object. It’s a fundamental physical quantity measured in cubic meters (m³) in the International System of Units (SI), but it can also be expressed in other units, such as liters (L) for liquids. In dimensional analysis, volume is described as a derived physical quantity ...
measure diameter of a small spherical/cylindrical body, measure the dimensions of a given regular body of known mass and hence to determine its density; and. measure the internal diameter and depth of a given cylindrical object like beaker/glass/calorimeter and hence to calculate its volume.
The weight of the fluid displaced is equal to the buoyant force ex-erted on the object. Thus, the buoyant force is given by: FB = ρgV. (10.2) where ρ (Greek letter, rho) is the density of the fluid displaced, V is the volume of fluid displaced by the object, and g is the acceleration due to gravity.
