Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location‚ seasonal variations‚ albedo of the place‚ contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary‚ operating at a smaller scale. Latitude

Investigate temperature change during a neutralization reaction Introduction: When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH-(aq)) from the alkali‚ forming water. For hydrochloric acid and sodium hydroxide: H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) → Na+(aq) + Cl-(aq) + H2O(l) Hydrochloric acid Hydrochloric acid Sodium Chloride Sodium Chloride Sodium Hydroxide Sodium Hydroxide Neutralization

Introduction To determine the effects of stressful experimental treatments on living membranes we are going to examine how fresh beets roots react when they are exposed to different temperatures. Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell 133). They organize specific chemicals and reactions into specific compartments within the cell. Generally‚ cell membranes consist of phospholipids

I will be explaining what a hurricane is‚ what was the damage caused‚ and how meteorologists track the hurricane. It got up to a category five and the top wind speeds were 175 mph. It was one of the worst‚ most disastrous hurricane of all time. What is a hurricane and how does it form? A hurricane is a type of severe weather that can rip houses to shreds and destroy many things with

Often‚ humans are blind to the idea that we are all one species‚ whether it be one person‚ or a crowd of people. Throughout the existence of mankind‚ many nations and civilizations have made history by slaughtering their own people‚ whether it be for superstitions‚ personal gain‚ or both. The Holocaust‚ one of the most violent genocidal events in the past century‚ has sparked many awareness programs to prevent another event of similar nature from happening again. Genocide is the act of deliberately

Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction

After 14 years of trial and error‚ he developed a process he called Appertizing. Fruits‚ vegetables‚ fish‚ or meat was sealed in stoppered bottles and the filled bottles were immersed in boiling water; the heat sterilized the bottles and food alike. Appert knew nothing of enzymes or bacteria‚ nor did anyone else in his day. He did observe that when food was heated in the sealed bottles‚ the food remained good as long as the seal was not broken. The food remained edible until the bottles were
