Thermometer

The world is constantly evolving and has been marked over time by significant political and social, cultural, and intellectual revolutions. A social, cultural, and intellectual revolution typically occurs over a long period of time and results in major advancements for the global population. Of all the social, cultural, and intellectual revolutions there are three revolutions: the Scientific, the Industrial, and the Agricultural (first and second) that are considered to have been highly…

products must be refrigerated. The refrigerator temperature must be below 38 degrees F. Freezers should keep foods at below 0 degrees F, and items in dry storage should be kept between 50--70 degrees F. with a relative humidity of 50--60%. A working thermometer must be kept in each unit at all times so that problems may be identified at a…

As a child you were probably very amused by the surreal properties of Mercury. Especially if you have ever seen it when it a Thermometer breaks as it floats in giant lumped up bubbles. Well there is much more than meets the eye in thermometers. For many, questioning things as a child is just a natural thing. For adults it becomes just something that is accepted, but their is many things that go into effect to make Mercury what it is. The book “The Disappearing Spoon”, by Sam Kean is a book that…

Italy on February 15, 1564. He was a gifted astronomer and physicist. Many of Galilei’s inventions resonate today, more than four-hundred years later. \This innovative man invented many things that are still used. He is the known creator of the thermometer (1606) and the telescope (1609). He also generated the concept of Venus’s phases (1610), Jupiter’s satellites (1610), Saturn’s rings (1610), and proved Copernicus’s heliocentric theory (1616). In his earlier years, Galileo’s father decided he…

then fill it ¾ full of room temperature water. Measure the mass again, and determine the water’s mass by subtracting the mass of the calorimeter from the total. 6. Calibrate thermometer as in experiment 2.1, then quickly take metal out of the pot and place it in the calorimeter. 7. Stir the water carefully with the thermometer and periodically read the temperature without lifting it out of the water. Continue until the temperature stop increasing, and then write…

was tested was 50oC, this is due to the potential of breaking the test tubes due to the extreme heat. The use of the same brand of thermometer to avoid error between the manufacturing of the thermometer could have produced more reliable and valid results. Each group should have tested the equipment before hand to see whether there was any differences with the thermometer and timer. Furthermore, a limitation within the experiment is the testing the temperatures in increments of 10oC, making it…

Place the test tube with cyclohexane into the apparatus. Insert thermometer and stirring wire in it. The thermometer should not touch the bottom of the large test tube. 4. Add ice and water into the large beaker. The level of cyclohexane should be lower than the level of ice-water mixture. 5. Stir cycloxehane gently but constantly. Use…

and the thermometer in the hydrogen peroxide 5. Once it reaches thirty degrees C test the solution. Test the activity by submersing the coffee filter in the potato solution for five seconds and dropping it in the hydrogen peroxide. With the timer for the coffee filter to sink and rise • Test the enzyme activity at forty degrees C 1. Fill the baby food jar with 2 ¾ tbsp. of hydrogen peroxide after cleaning 2. Fill a cooking pot with water about four centimeters deep and put the thermometer in it…

records. When the patient knows how the tools work, the patient will understand their vital signs better. Starting with the temperature, there is a tool called a tympanic digital ear thermometer, which is battery operated. This is a way of measuring the body temperature inside the ear. The tympanic digital thermometer is a hand held device with a “window” showing the temperature. The window is a screen that displays…

ml ) How: Each trial will have a different amount of alcohol using the measuring beaker to measure amount Why: To compare the difference of heat produced Dependent variable What: The amount of heat produced during combustion How: Using the thermometer to find the temperature of water plus using calorimeter to find precise amount of heat/energy Why: To find out the heat of propanol Controlled variables What : How :The apparatus to keep experiment insulaHow: Use same equipment that we…
