How Surface Area Affects the Buoyancy of Wood Essay example

4. Predict: What do you think is the density of the whole block of Styrofoam? 0.2 g/cm3

because each of the objects displaced the water by 1 mL, their mass over that mL is their density.

Density is the amount of matter per unit of measurement (Merriam-Webster. Merriam-Webster, n.d. Web. 26 Aug. 2016.). If water has a density of 1.0 g/mL and you place a substance with a density of 1.8 g/mL the substance will sink because it is denser than water. Density is often measured in g/cm^3 or g/mL because the formula for density is D=m/v.

E. What would happen if you dropped the object into the beaker while using the Archimedes’ Principle method instead of submerging the object?

A. How did the experiment in Part I demonstrate surface tension? Use your experiment observations when answering this question.

Attraction between water molecules which allows insects and other objects to float a top the water

When an object falls onto the surface, it has to push the water molecules apart. If the effect of the weight of the object is insufficient to match the attractive forces between molecules in the surface layer, the object will not enter the surface.

Difficulties in the experiment arose when inverting the buret and completely submerging it into the beaker of water. This is a likely place for error because

Abstract: The objective of the lab is to determine the volumes of the polystyrene spheres with three different measuring tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The experiment is meant to help understand the concept and application of precision and accuracy in experimental measurements. Accuracy is a measure of how closely the results of repeated measurements are to the true value of what is being measured. Precision is the variability in the results from the repeated measurements, and how close the repeated measurements were to one another. In this lab, the method for measuring the volume of the polystyrene spheres is done with the previously stated tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The standard deviation for the entire classes volumes and masses are recorded to determine the densities.

However, there are some other factors that affect the fall rate of the marble, including; size and the shape of the marble. Therefore, the marble undergoes drag force and the effect of gravity, which all accounts for hydrodynamic forces. Hydrodynamic forces are the forces which slow the snow as it moves through liquids. In this experiment, turbulent flow can affect the snow’s timing to reach the base of the breaker in water as the flow of the fluid is

Since this solid block is more dense than water (1.536 g/cm3 > 1 g/cm3) it will sink.

In the fourth stage of this experiment, the density of a gas was determined. A 250ml flask was weighed with an empty rubber balloon and the mass was recorded.

not float like a balloon or sink below the line and should be formed from the top and not the bottom.

After that, it is crucial to convert the mass to volume. The water density at a temperature will aid this process. The compliance of the Volume Occupied by 1.000g of Water Weigh in Air table is deemed necessary throughout the comparison.

3) In this experiment, only the forces on the plane surface were considered. Do the hydrostatic forces on the curved surface of the quarter-circle block affect the measurement? State why or why
