1. Temperature: Put some hot water‚ warm water‚ and cold water in three bowls. Just use water from your faucet‚ and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds‚ place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water‚ my finger felt a hot

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice

The average temperature in Santiago is 14.4°C with January being the warmest at an average temperature of 21°C and June and July being the coolest months‚ both with an average temperature of 8°C. For what is considered to be fall and winter in the northern hemisphere‚ is spring and summer in the southern hemisphere‚ therefore that is when Santiago’s climate is at its peak. It can be noticed that from January to June and July‚ the temperature starts to change at a not so slow

While both David Sedaris and Dave Barry use various types of humor‚ such as hyperbole and sarcasm‚ in their essays‚ one is commenting and criticizing on ironic situations people can relate to and the other shows how to turn uncomfortable situations around. In the essay “Me Talk Pretty One Day” Sedaris uses hyperbole to add humor in his essay‚ “Her rabbity mouth huffed for breath‚ as though the appropriate comeback were stitched somewhere alongside the zipper of her slacks‚ “(pg 12).

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

You may be wondering what diffusion‚ tonicity‚ osmosis and semipermeable membrane is. I’ll start off by explaining semipermeable membrane. A semipermeable membrane relates to the dialysis lab #1 because in dialysis tubing is considered semipermeable barriers. Semipermeable membrane is a membrane that allows passage of some particles but not others. (Lab manual) Diffusion on the other hand‚ is a form of passive transport where particles move down their concentration gradient from a region of high
