Relating Mass and Volume Question: What does mass have to do with the amount of space (volume) a liquid occupies? Hypothesis: I believe that the mass and volume is related because they both rely on each other for their purpose. If we fill the cylinder to a certain measurement (volume)‚ then the mass will grow with it. There is a balance. Materials: - Distilled water - Corn syrup - Saturated solution of salt water - Triple beam balance - 150 mL (or larger - Small plastic pipette - 150 mL beaker

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show

Structure of Gaseous Exchange Surfaces in Humans‚ Fish‚ Insects and Frogs Gaseous Exchange is a biological process where oxygen diffuses into the body or bloodstream and carbon dioxide diffuses out of the body or blood stream. This process is different for Humans‚ Fish. Frogs and Insects. Humans: In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million

Question 1 Surface level diversity Surface level diversity are those differences that are easily noticeable such as age‚ gender‚ ethnicity/race‚ culture‚ language‚ disability etc. Surface level diversity is easy to be measured and managers/recruiters can fall into the wrong practice of discrimination based on these factors. For example‚ thinking that performance degrades with age‚ they might prefer younger workforce. Surface level diversity is often difficult to change. For e.g. racial differences

Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs

Surface Tension of Water I. Purpose How does adding soap to water change its surface tension? II. Background Adhesion is the bond between two substances of different makeups. In water‚ adhesion allows it to stick to other surfaces. Cohesion is the bond between two of the same substances. A hydrogen bond is a type of cohesion in water in which the hydrogen atoms of one water molecule being attracted to the oxygen atom of another water molecule. In water‚ each molecule in the middle is pulled
