Volume One

16, 2015 CHM 23000-23   Introduction Matter is described as any object that holds mass and volume. Mass is the amount of matter in an object that is usually explained in the unit of kilograms. Volume is defined as the amount of space that matter takes up usually described by the unit liters. While mass and volume relate to matter, it also relates to density. Density is the amount of mass per unit volume. Common units for density include grams per milliliter for liquids, grams per centimeter for

Objective This experiment will involve measuring the volume and mass of a cylinder, a sphere and a wooden block. Based on the mass and volumes of these objects, the density of these objects can be calculated. The equation for the density of an object is density =mass/volume. In the density equation there is a direct proportional relationship between the mass of an object and its volume. For instance, if an object has its mass decreased, its volume will also decrease. The experiment used a Vernier

Comparing the volumes of a round and square donut. Which of these two donuts better fits in a dozen box? Christina Tannous Supervisor: Mr. Omar Rachmani January 25, 2015 Everybody loves to have a donut every once in a while. It’s a tasty desert that nobody can deny; children all the way to adults love it. I am personally a huge donut lover! When I usually walk through the mall I find different coffee shops selling square donuts, and not only round ones. This is what sparked the idea in my

The volume of the Jelly Marbles that sat in the water have a volume of 1.02 milliliters. Trial 1 for the Jelly Marbles in the food coloring had a volume of 1.03 milliliters and trial 2 had a volume of 1.12 milliliters. The volumes for trial 1, 0.17 milliliters, and for trial 2, 0.03 milliliters, has a big difference. The density for the Jelly Marbles that soaked in

Pressure vs. Number of Particles Lab Report Introduction: The experiment deals with many different parts and one of them is gas, a substance that moves freel through the air and their particles are stread farther away from each other when compared to the other states of matter. The difference between the states of matter are how close the particles are to each other. The experiment was completed to find how pressure affects the number of particles. Pressure, which is the force exerted on an object

area to volume ratio on the rate of diffusion is investigated. Four agars containing phenolphthalein, an indicator that turns colorless in acid, each ranging in size were used. In this experiment, the agar cubes represent cells and the time it took for cubes to turn colorless shows the rate of diffusion. Next, the cubes were placed in a beaker and just enough hydrochloric acid was added to cover them. Then, the time it took them to turn colorless was measured. It was observed that when volume increases

Substances, including water, ions, and molecules that are required for cellular activities, can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration

to dynes/cm2. The values that were calculated appear to be very similar to one another. The average ∆P are found to be ∆P= 4900(±200) ∆P= 4600 (±90) for both sides of the capillaries. The values are indicated in the table below. Table 1. Trials 1-5 indicate that one side of the capillary is tested. Trials 6-10 indicate the other side of the capillary is being tested. Both radius values end up being very similar to one another, which indicates that both sides are fire polished. The capillaries
