Sea surface temperature

all gases occupy 22.4L in any container under standard temperature and pressure. This information could be valuable in many ways. For example, it proves Avogadro’s Law which states that at a standard temperature and pressure, one mole of any gas will occupy the same value which is 22.4L. Like a puzzle piece, once discovered, it…

Cold Packs What are cold packs used for? 1. Cold packs are often used to treat painful injuries, such as a sprain or to ease swelling from minor injuries; cold packs come in many different variations some are made of gel that turn into icepacks when stored in cold, dry places, others are designed to freeze when pressure is applied to the gel pack where no freezing is required, the cold pack is used to slow down the blood flow to an injury so it doesn’t potentially get any worse. How the contents…

Recent studies have shown that direct physical contact of the human body with the surface of the earth (grounding or earthing) produces profound quantifiable physiological effects. A reasonable hypothesis to explain the benefits is that a direct connection to the earth and the human body allows the abundance of free electrons to flow from the ground to the body. It is proposed that because there is sufficient evidence to suggest that earthing has positive effects on physical health, the influx…

a chemical reaction as bubbles indicate a formation of gas, and the formation of gas is a sign of a chemical reaction. Moreover, a new substance was produced, evidence that a chemical reaction occurred. Additionally, in the lab, we recorded the temperature of the water…

measuring saturation temperatures for six different solution concentrations. We form a group of four and were assigned to work on series one while the other group work on series two. Throughout the lab, we set a hot bath water temperature at 85 degree celsius which affected how potassium nitrate dissolves in water and changed the saturation temperature. In addition, our group discovered that the mass of test tubes plus potassium nitrate relates to the saturation of temperature. The lighter mass…

In this experiment, the effect of temperature on reaction rate of enzyme will be studied. Peroxidase will be used as test enzyme and the variable to be studied is temperature (°C). At first, the experiment will be carried out at room temperature of 20°C. The temperature of the experimental setup will then be increased by keeping the reactants in a water bath at a temperature of 50°C. The enzyme catalysed reaction rate will also be studied at a lower temperature by placing the reactants in an ice…

an hour to see how much of the water has frozen.(if any) 3. Once the distilled water has gotten below zero (if it has not started to freeze) leave it in for another 30 minutes to 1 hour, then take it out and pour it onto ice or bang it on a hard surface and hopefully you will see it start to freeze. 4. Try the experiment again to see if you get the same results. Data Freezing points of tap water vs distilled water Time in freezer Tap Water Distilled water 30 minutes Water on top…

had already contracted from being put in the cold water. The particles would have to expand even more now to not fit through the hoop. d). To make sure the experiment went well, we made sure the ring stayed around the same temperature as much as possible. If the temperature of the ring changed a lot, the brass ball might end up fitting when it is heated or the ring might be too big for the ball after the ball is cooled. This might affect our results by thinking that the brass ball contrasted a…

For example, when the process is endothermic, the kinetic energy increases since the temperature increases, but remains constant at a phase change. However, during an exothermic process the kinetic energy decreases along with the temperature and during a phase change the energy and temperature will remain constant. The kinetic energy is opposite for each of the curves because as the kinetic energy decreases during the exothermic process…

The Tundra is the coldest biome out of all of them. The word tundra means “treeless plain”. The tundra is known for its frosty landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. The tundra is characterized into two types: arctic tundra, and alpine tundra. There are many different characteristics that make tundra such a unique biome. The extremely low climate and low biodiversity are the most known. Most of the energy and nutrients…
