Effect Of Salt On Cooling Rate Of Water

Newton’s Law of Cooling The main purpose of this experiment was to find the positive constant “K” for different liquids in the Newton’s Law of Cooling equation, in order to determine when it was safe to store food products in commercial restaurant after cooking. The high risk temperature for bacteria growth is between 5 and 60 degrees. However putting hot food into your fridge before this point can cause food poisoning especially in deep containers, which is why it is vital that food companies...

Effects of Salt on Freezing Point of Water

Blank 1 Blankity Blank Blankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment, you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid, the temperature at which that liquid freezes decreases, because the molecules of the solute become attached to the water molecules, making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing...

Salt Water

SALT WATER Introduction: Salt water refers to water that contains dissolved salts, known as saline water or seawater, water from oceans or seas. It is a home to varieties of aquatic animals, for example, fishes and snails. Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh water they can not adapt the environment led to die to them.

Fresh Water Cooling System 1

Fresh Water Cooling System Introduction Although there is an abundance of free sea water available, marine diesel engines do not use it directly to keep the hottest parts of the engine cool. This is because of the corrosion which would be caused in the cooling water spaces, and the salts which would be deposited on the cooling surfaces interfering with the heat flow. Instead, the water circulated around the engine is fresh water which is then itself cooled using sea water. This fresh water is treated...

An Experiment to Determine the Heating and Cooling Curves of Water

NS 10.5 (pg 1 of 2) Heating and Cooling Curves What happens when we heat a sample of ice that is initially at -15°C? The addition of heat causes the temperature of the ice to increase. As long as the temperature is below 0°C, the sample remains frozen. When the temperature reaches 0°C (the melting point of water), the ice begins to melt. Because melting is an endothermic process, the heat we add at 0°C is used to convert ice to water and the temperature remains constant until all the ice...
