What is the effect of water temperature on a minnows lifespan? Purpose The purpose of this report is to see the effects of the change in water temperature to a minnow fishes behavior and how long it lives. Background When the temperature of water increases, the amount of dissolved oxygen and other gases will decrease, making it harder for aquatic life to survive. This means, colder waters can hold more dissolved oxygen than warmer waters. But fish thrive in different temperatures. While some…

saturation point. The sodium acetate in a supercooled state will rapidly change into a solid with the addition of physical energy or a nucleation site. During the transformation of the liquid supercooled solution into solid crystalline formation produces heat in an exothermic reaction, hence the name hot ice. Enthalpy (ΔH) if negative indicates an exothermic reaction. ΔH = energy used in bond breaking reactions − energy released…

There are many factors that affect the rate of a reaction and they can either be fast or slow. The factors that affect the rate of a reaction are nature of reactants, concentration of a solution, presence of a catalyst, surface area, pressure of gases, temperature etc. These reaction rates may have positive or negative effects in our everyday lives. Today, I will be talking about how temperature, surface area and concentration can have a role in our everyday life. Firstly, a factor that affects…

save a lot of money. Your home buyers insurance can cover your heat pump. There are many ways that you can benefit from getting a heat pump.

called glassblowing where artists known as glassblower/gaffers basically blowing air into a 6 ft long pipe that has heated molten glass at the end of it which causes the glass to become larger and shapeable. During this process they will continue to heat the glass in a furnace while in between applying steady rotation by rolling it on a table to to form a shape. Sometimes they may even add some color by rolling the hot glass different colorful materials and then heating it in the furnace once…

The Fresnel lens was first invented by French physicist Augustine Fresnel and at first were a simple, beehive resembling contraption with a light source in the middle, but then it developed into something that mirrored a bull’s eye with a more powerful beam (Fresnel Lenses). The Michigan Lighthouse Conservancy went on to explain that the Fresnel lens was created for the sole purpose of installation within lighthouses. The efficiency and power of a Fresnel lens allowed its design to emit a source…

in Task 1. In any office, the room can be too warm when working as a result of the amount of people in room and the number of computers and printers which are generating heat. An overheated office can result in employees feeling too warm which will leave them perhaps too tired or uncomfortable to work. In order to reduce the heat in the office so that maximum work can be carried out, a number of strategies can be deployed. For example, you could open a door, perhaps open windows or remove items…

activities, the heat of the day could put you at risk. Overheating can lead to heat exhaustion or even a heat stroke. Knowing the signs could save your life or others. Heat exhaustion and heat stroke may be caused by a number of reasons, while the repercussions can be detrimental to health, and these conditions affect both humans and animals.
