Volume

The purpose of this experiment, “Units of Measure - Weight, Volume and Length” is to become more acquainted with the different types of equipment such as pipettes, graduated cylinders, and more objects of that nature. The experiment concentrates on the measurement of objects using the metric system and relating it to scientific notation, significant figures, and more. A large component of the experiment revolves around the concept of ‘accuracy’ and ‘precision’, which is meant to be learned through

household chores etc. Though, it is not advisable to drink rainwater, it can still be used for cooking after being boiled or cleansed. This report will include investigating several things such as the sizes of the tanks required for a certain volume of water, the volume of water that should be used during different times of the year and so on. Through this task, common questions like- What is the capacity of rainfall that my roof can catch? How often does rainfall occur? / What is the average rainfall

difference between softwoods and hardwoods, and how density and strength are related. In this lab, we utilized 10 different samples of wood blocks. By measuring each sample’s Volume (Length x Width x Height) and mass, we were able to determine each sample’s density (Mass + Volume). The chart below describes our findings. Sample Volume (〖cm〗^3) Mass (g) Density O 18.93 16.04 34.97 2 11.40 15.26 26.66 27 13.44 13.13 26.57 19 10.47 9.59 20.06 25 11.91 10.88

by the substance. Density is found by using the formula mass divided by volume. Identifying the mass and the volume of each object will help to identify if the objects are made of the same material. Through the initial observations of the objects, the conclusion was made that each one was made of different material. The purpose of the experiment carried out was to find the mass of each object and then divide by its volume, thus giving the density of the object. Two methods were used to find the

Discussion: Define and explain density in your own words. Density is calculated by dividing its mass by its volume (D=M/V). Density also describes how compact a substance is (amount of space occupied within a certain area). What is the difference between mass and density. The differences between mass and density are that mass is the amount of matter in an object and density is a measurement of how close the molecules are packed tightly together in a certain amount of space. In this lab, can

Careful emptying of the plastic bottle was ensured to preserve accurate volume measurements in the subsequent trials. The mass of the empty, capped plastic bottle was determined using the analytical balance. Afterwards, 25.00 mL of Light Coke® solution was measured in the burette by filling it completely (50.00 mL), then draining

from working on their own, a ventilator is a life-saving replacement. The volume of oxygen in the cylinder is depressed down and the pressure increases moving the oxygen through the tubes into the patient. The plethysmography technique applies to Boyle’s law and uses measurements of volume and pressure changes to determine lung volume, assuming the temperature is constant. The plethysmography technique measures the volume of all compressible gas in the thorax, including gas trapped behind airway

The Relationship Between Density and Sugar Content Danielle Shaub Partners: Emily Alexander, Bill Dempsey, Shayla Ho Lab Performed 03/11/15 & Lab Report 04/07/15 Abstract: Using solutions of sugar and water alongside cola, density and percent sugar can be related. The purpose of this lab is to discover how and with what benefit these factors can be related. Using assorted measurements and the standard curve of the calculated densities and percentages of sugar solutions, it was learned that cola

used the most accurate and precise apparatus possible to ensure the results obtained were accurate. For measuring the gas volume, I used a gas syringe. A gas syringe is a special low friction syringe for measuring the volume of gas produced or to insert gas into a reaction. I chose to use the gas syringe as it is very appropriate and accurate, allowing me to measure the gas volume to an accuracy of 0.5 cm3. My choice in using the gas syringe as a measurement tool allowed me to ensure my results were

One good thing was that the volume of the film canister was measured properly. Some problems were that when the water in the canister was poured into the graduated cylinder, a few drops of water spilled back into the tub of water. Also on the graduated cylinder had lines to the nearest millimeter but the meniscus was in between two lines so the measurement was not completely accurate. There were a few extraneous variables. One of the extraneous variables was the volume was calculated from a separate
