Additionally, the data on the height and the diameter of the bullet shaped object was collected and tabulated. In the second experiment, the data on the sphere’s mass was collected as mass 1 to mass 5. The fourth experimental that was needed in the experiment was the diameter for the five spheres which were taken as diameter 1 to diameter 6
We took the density of the clay as Mass per Unit of Volume. The formula that was used in calculating this was with an SI unit of . In the experiment, the propagation of errors was calculated from the approach of partial derivatives. The formula for this was
The standard errors for the experiment were demonstrated by . The standard error was obtained through the computation of standard deviation from the various measurement. We later calculated the standard deviation with the help of a graphical analysis program. The standard deviation was denoted as
N is taken to mean the measurement’s number of x. x and y are taken to represent their mean values. The uncertainties in the end outcome were reported with one significant number. It was assumed that the final average value is equated to the number of decimal points found in the uncertainty.
The equipment that were used in the experiment include; a plastic bag, hollow cylinder, bullet shaped object, Vernier’s calipers, balance, and a set of masses. In the first experiment we determined the volumes and the standard error for the hollow cylinder, bullet shaped object, and the triangle prism (Price, 889). The following equation was used to calculate the volume of the hollow cylinder
The Vernier calipers was used to measure the pertinent dimension of the object. The dimension of the Vernier was 0.05mm. The five measurement of the provided object was measured. After taking the five measurement, the mean values for the dimensions were also determined. The standard deviations for the dimensions for the hollow cylinders was then determined. The

Vital capacity of male and female was compared and the effect of partial pressure of carbon dioxide in the inspired air along with the effect of hyperventilation on breath holding limit was also measured. Carbon dioxide is one of those factors whose presence in the inspired air directly relates to the respiratory rate and tidal volume.
Density Lab Report Introduction A density of a substance pertains to an intensive property of matter which relates mass to volume, where such density equals mass (m) per unit of volume (v). Intensive properties are independent of the quantity of substance and in the experiment, Archimedes’ method of displacement ought to be employed in determining the density of a penny (Adam, 2012).
Acid base titration Aim The experiment intended to ascertain concentrations of Dilute Hydrochloric acid and Dilute Sulphuric Acid solutions by conducting Acid-Base titrations. Hypothesis Phenolphthalein change of color from pink/purple to colorless signified a transformation of the solution’s nature from being basic to acidic, which was the reaction’s endpoint or neutrality point.
This is done when we breathe. We inhale oxygen (O2) and exhale carbon dioxide (CO2). In this manner air is distributed to many parts of the human body. The Respiratory system also comprises the olfactory receptors involve for the sense of smell.
"The respiratory system helps regulate the balance of acid and base in tissues, a process crucial for the normal functioning of cells.
The experimenters determined that concentration and content do not affect nappy weights.
Infants, compared to adults, possess a greater volume of percentage of water in their bodies (as much as 75%). They are thus sensitive to changes in humidity,
Then fill the pipette/burette with water till the water reaches the mark on the burette/pipette. Thereafter, transfer the measured water into the canonical flask. Now weigh the canonical flask when it is filled with water. Repeat the
The results yielded a significant relationship between mass and volume at ‘0.05 level of significance’ and a corresponding p value of 0.0009. The results also identified an experimental density of 7.54 g/mL for the pennies
Error propagation entails combination of individual uncertainties as a means of determining the accurate value of an experimental error. Aside from error propagation, lab experiments also benefits from the
