The observation from what I saw was impressive to be seen in the class.In the research I learned that dry ice was made from degrees that are below than 10 degrees.You had as welll put in water to make the smoke effect work.Another thing is that be sure not to touch the plate beacause the plate is hot.It started boiling and crazy as well.
Later on in the project there was another one there.One on the plastic and the other one that was ilumatialn.They both reacted the same away as well.When put the water in there it started some kind of smoke.Then started to smoke even more after a couple minutes.
After a while if you blow in it it starts the smoke again.I researched it that ice is made from coldest it can in order to react.Moreover I saw people
When the flame was blown out and the glowing wooden splint was placed halfway into the test tube containing H2O2 and MnO2 crystals, the splint reignited and caught flame once again. This demonstrates the decomposition of H2O2 into water and hydrogen. MnO2 is a catalyst that increases the rate at which H2O2 decomposes. Adding oxygen to a fire will cause it to burn faster and hotter and the oxygen rich test tube allowed the splint to reignite.
8. Put the closed flask into a water bath at room temperature in a 1 L beaker. Ensure that the entire flask is covered. If the flask begins to float, clamp it down. Put the temperature probe in the water bath. Using a pipet, add some boiling water from the hot plate to the water bath until the temperature of the water bath increases by 3 °C. Use the temperature probe to stir the water bath. Once pressure and temperature measurements stop changing, keep the data. Record the air pressure and vapor pressure for this temperature.
This smoke bomb lab helped me understand chemical bonding and reactions by starting from the very beginning with mixing the nitrate, sugar, and melted crayon. Mixing them formed a texture almost like powdery peanut butter with some liquid which was actually pretty interesting. The second chemical bonding I seen was that, once putting the solution in the tin-can and it started solidifying due to all the stuff we mixed together. It didn’t take long at all for it to start forming into a solid. When we went outside and lit the wick on fire showed the main chemical reaction throughout the whole experiment. The nitrate reacting with the lighted wick started a big fire in one of the groups cans but some of the other groups bombs didn’t get to light like it was supposed to and the wick just burned out. I was one of the groups whose bombs didn’t work properly. I think it’s because we didn’t put the wick in deep enough to our solution so when we lit it the fire just burned out before going into the solution.
Plasma is one of the three components of blood and contains all the clotting factors found in blood. From the plasma many different products are manufactured, these are fresh frozen plasma or when the plasma is split into its different components. Plasma is obtained from voluntary donors who donate just plasma via an apheresis machine or they donate whole blood which then gets centrifuged to separate the plasma from the rest of the blood.

The reaction between the sugar in the gummy bear and the melted potassium chlorate in this experiment is an example of an exothermic reaction. An exothermic reaction is a chemical reaction that releases energy as heat or light. When potassium chlorate is melted, it produces potassium chloride and oxygen. When the sugar and oxygen react, energy accumulated in the chemical bonds of the sugar molecules is released. This is a combustion reaction, an exothermic process in which a substance reacts specifically with oxygen to produce heat, water, and carbon dioxide. During the process of combusting the sugar in the gummy bear with oxygen, the products formed are heat, a purple flame (light), carbon dioxide, and water.
The Iceman constitutes the first prehistoric human ever found with his everyday clothing and equipment, and presumably going about his normal business; other similarly intact bodies from prehistory have been either carefully buried or sacrificed. He brings us literally face to face with the remote past (Paul Bahn, 1996). When Otzi died up on the mountain 5,300 years ago, his final resting place was a trench that ironically saved him. With his body face down over a bolder, large rocks lined the small nook he was in. Eventually, massive amounts of snow fell over the body, the snow compacted and froze forming a glacier. Over thousands of years the glacier built up layers and inched its way forward. Because of the trench Otzi was in, the ice creaked along above him, completely shielding him from any outside influences for many years.
Experimental Summary: First, my partner and I put the marshmallow and cheese puff on T-pins and used the Electronic Balance to measure the mass of each of them. Next, we put 100 mL of water in the 100 mL Graduated Cylinder and poured it into the 12 oz. soda can. We measured the temperature of the water with the thermometer. After
INTRODUCTION The winter season can be a major hassle for some people while others just have to deal with a slight cool down in temperatures. Over the northern portions of the country, people are faced to deal with the harsh conditions that Mother Nature has in store. Some winter seasons are less brutal than others. Besides the typical storm systems that come through the area and drop different types of precipitation whether it is snow, sleet, or freezing rain, there’s another weather event that affects not everyone in the country, but primarily around the Great Lakes.
Due to a series of snowstorms that hit Sierra Nevada recently, the snowpack is higher than the average for this time of the year. This is a milestone for California, who has been in a severe drought for the past year. The storms have increased the snowpack levels of the mountain that hasn’t been seen in two years in California.
Genesis 1:26 – And God said, “let us make man in our image, after our likeness: and let them have dominion over the fish in the sea and over the birds in the sky and over the livestock and all the wild animals and over all the creatures that move along the ground”.
It is a cool early afternoon in the middle of winter. Frost is flaking on the tips of the grass blades, and the sun is shining off the stark white frost. We are in southern Wales at an almost empty rugby stadium. My mother and I are on a tour through this stadium. There is an occasional speech from the tour guide, but after every one of them there is awkward silence as we shuffle along. My mom is wrapped up like a pig in a blanket. If there was anything she would rid from the world then it would certainly be the cold. She always likes to wear accessories with her outfits. A scarf is wrapped around her elegantly and a woolen hat sits on her head.
Also, when we put the insulation cans in warn water the water heated up the can. And lastly, in the insulated can experiments, both cooling and heating, when the cans temperature was changed it in turn changed the air temperature
Electronic cigarettes have a coil that heats the liquid into vapor. This method of eliminating cigarette smoking is more convenient for people in this day because there are shops that do sell these electronic cigarettes. Since they are convenient, it is increasingly popular worldwide and more smokers might be thinking to make the switch. With this method, smokers can reduce the cigarette consumption and continue to have the “smoking” experience with less heath risks. Although there is not too much research on it smokers should make the switch because it is healthier and cleaner for the environment. When you take a puff on the electronic cigarette, the battery heats up the nicotine, which creates vapor that is then inhaled into the lungs. Smokers should be allowed to smoke electronic cigarettes in public, also known as “vaping”, because it is safer and won’t cause a fire as fast as a cigarette would. Although it does have a battery and batteries can explode due to having the battery being used for a long period of time. You would be able to notice it getting hot before it actually catches on fire, due to the heat it is producing. There are now new
Freeze drying, otherwise known as lyophilization, is a form of drying that is done by freezing a wet substance and allowing the ice to directly sublime to vapor by exposing it to a low-pressure amount of water vapor. This method of drying takes place in a special type of vacuum desgned for this method. Freeze drying is used in many instances, often as a means to preserve material or decrease the weight of that material; thus allowing transportation of certain substances to become less difficult.
