the ice in the calorimeter. Because ice takes up more volume per gram than liquid water, this

4. Continue this process until data is obtained for at least six different temperatures. Be sure that the temperatures represent a large range of values in order to help you answer questions about the relationship between temperature and volume.

13. Calculate the change in temperature for the water caused by the addition of the aluminum by subtracting the initial temperature of the water from the

Step 2: The volume of both tanks is equivalent to 84,780. You utilize the recipe, and module the numbers to get the answer.

3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

Water is essential for life as we know it on earth. It is used by plants

4. Remelt the contents of the tube and add the counterpart component based on the given schedule. Ask the demonstrator to adjust the cooling water between mixtures. During the experiment, record and plot the data obtained for all mixtures listed. The experiments are stopped as follows:

As I sat next to the loud river that was bursting out of the Sylvan Dam, I noticed the water was in an invariable battle with the rocks, crashing and thrashing against each other like medieval warriors scraping for land. I looked around the edges of the river to see the copiousness of colors from the trees contrasting the sinister blue water. The rapids put off a pleasant and dulcet sound that ultimately ended in me having to relieve some building pressure down the trail. After returning to my riverside view, I noticed that farther down the gleaming river, fish were jumping and flipping like delicious pancakes on a griddle. Making the split-second decision to fish, I sprinted to my 1999 black Chevy Silverado, unlatched the tailgate and snatched all of my waterproof fishing gear. Slipping on my Mossberg max 4 Camo Gander Mountain guided series waders is no easy chore. While looking like the most incapable human being ever I finally managed to slip on the foul scum smelling waders that I so dearly should have washed. Feeling like a professional mountain climber, I started scaling the steep inclement of the river bank. Stomping my insulated waders into the frigid dour murky water, I ventured my path out onto a construction of rocks forming a beautiful approach for spotting fish. I released my light green jointed shad Rapala from my St. Croix Legend Elite spinning rod and casted the shad into pooling backwater just off of my rocky approachment. Feeling the vibration of the shad through my rod, smacking against slime covered rocks and ripping through dense weedy areas. I felt aspirant to not get hung up on a rock resulting in a line break, I successfully retrieved my lure. After casting and reeling my line several times and just started zoning out, I was abruptly startled to hear a ruckus coming from the west side embankment. Glancing quickly back to the water to see where my lure was only to hear a loud splash coming from the same place where I first noticed the ruckus. Three deer, with golden brown fur coated enrolled into the water. Realizing that the leaders of the small herd were both doe’s and a younger buck eagerly followed. The buck had a nice six-point rack, with long tines and a wide spread. He kept his

To do this I found the length, width, and height of our boat. To do this we used the centimeter size of a yard stick and measured __cm, __cm, and __cm. Once we multiplied those three numbers together, the solution for our boat´s volume was 282,240 cm³. Once I knew the mass and volume, I could use the formula mass divided by volume to calculate density. After dividing the two, I got 8.32610-3 cm3.I know that in order for my boat to float, this number has to be less that one, which is was! Next, since I knew the boat would float by itself, I needed to see if it would float with Breanna in it as well. To do this I had to recalculate the mass of the boat from 141 pounds to kilograms. I multiplied by .47 and moved the decimal, like I did previously, and got 66.27 kilograms. Next, I repeated the same process used at before to recalculate density and got .22510-3cm³. Once again, I was proud to find that based on the calculations, our boat was supposed to float, and it did!

These coolers have a unique feature that ensures the cooling performance is extreme when compared to other cooler styles. It takes full advantage of the “Cool Riser Technology”. This means that it has an elevated design, which will promote airflow under the cooler.

The purpose of this lab is to determine whether a liquid is hard water or not.

The temperature-time plot gotten by applying a lumped-parameter analysis (Equation 6) to the Aluminum cylinder was compared to the plot obtained from the thermocouple located closest to center of the cylinder. This thermocouple is chosen for comparison because it is located farthest from the heating source and will have a temperature history that differs most from an ideal lumped system. With this thermocouple, we should therefore obtain the maximum error associated with applying a
