5. Which Fed tool do you think is most important, and why? (2-4 sentences. 1.0 points)

Next, I poured distilled water just below the 250ml mark on the neck of the volumetric flask.

2. Determine the room’s air temperature, and also measure the diameter of the glass tube. Record the data.

First, I will get my materials and set up the scale and 10 mL cylinder and refraction cell. I will check the size of the graduated cylinder to find out the volume. (LxHxW) That will equal 40.5mL for volume. I will see how much the cell weighs alone, and then I will 0 out the scale to see how much the water weighs. Then I will see how much the water and the cell weigh together. I will do this for the cell and cylinder. I will check to see if the density I calculated is what it is supposed to be at 1.00.

Insulate - to cover, line, or separate with a material that prevents or reduces the passage, transfer, or leakage of heat, electricity, or sound (Insulate ,2015, pg.1). In this experiment insulation is the main topic. Insulation is used in many things: a house, a refrigerator, walls, clothing, and types of drinking cups. Installation can be made of materials like styrofoam, plastic, and fiberglass. These can be used to keep things hot or cold. Insulation is most commonly for heat and maintaining heat energy. This experiment tests the insulation of several cups and how they keep liquids hot. Each cup used in the experiment has some insulation. The cups have different amounts of insulation. Each of these cups are generally used as insulators for many liquids.

To start off the lab we did simple measurements with two different rulers, both measuring in centimeters but had different amounts of divisions on the second one making its measurements more precise. The first item to measure was a 13 x 100 mm test tube, again using the two different ruler’s metric ruler A and metric ruler B. After recording the measurements with the accurate rounding, we did the same steps to measure the diameter of a watch glass and an evaporating dish.

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.

1.) Measure out 20ml out of the water and place it into a glass beaker

The colorful look of dichroic glass is only achievable through thin film physics, and process that gives bubbles their rainbows and dragonflies their colorful wings (Smedley). In occurs when one light wave hits a thin film. Part of the wave is reflected as some continues to travel through the film, diffracting slightly as it enters the new medium. The continuing wave then encounters another new medium where it is reflected back. This reflected wave then interferes with the first reflected wave. This causes the colorful spectrum that can be seen in a dichroic glass

Trial 1: A dish was filled with approximately 2 cm water and a candle mounted on clay was place in it. The candle was lit and a jar was placed over top of the candle so that it was resting on the dish. When the flame went out the water level inside the jar was measured. This process was repeated three times.

On page 203 of Artforms is the site-specific work of art called Eavesdropping. This piece was created by Amalia Pica in the year 2011. It is composed of forty standard sized drinking glasses. Each glass is affixed to a white wall with glue, so that the rim of the glass is against the wall. The glasses are a variety in color, ranging from purples, to blues, to reds. Some of the glasses have no color and are simply clear. Most of them have no pattern, but there are a couple glasses that have a patterned design.

Have you ever wondered why glass bottles made a sound, kind of like a music note? Well, this paper will explain how this works. The paper will be talking about sound, sound waves, standing waves, musical note names and frequencies, resonance, and closed-end air columns. Closed-end air columns will be a main focus in the paper, studying the physics behind it. Glass bottles are an example of a closed-end air column. Therefore, the more water inside the bottle, the lower the note, and less water would be a higher note.

The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:

In this experiment, The purpose of this experiment is to investigate the measurement of the actual volume contents of volumetric glassware. In the beginning of the experiment, the volumetric glassware should be clean and dry before used. The volumetric glassware, measuring cylinder and pipette should be handled with care and all the precautions were be taken during the experiment was held. This was to ensure to avoid any errors such as parallax error especially while reading water meniscus. This experiment must be repeated three times or more and take the average reading to get more

I decided upon my hypothesis for the reason that as water is added to the wine glass, it will result in a greater mass. This greater mass should result in the glass vibrating in larger and further apart waves. The larger and further apart the waves are, the lower the pitch of the sound, making the frequency proportional to the amount of water.
