capacity 1. heats up and cools at a faster rate. For example, metal like iron, steel, copper and aluminium is used as pots and pans because they can be quickly heated up when there is only small heat absorption. 2. sensitive to temperature changes A thermometer has low specific heat capacities so it enables heat to be easily absorbed and released even when small quantities of heat are…
Merriam-Webster defines hypothermia as a condition in which the temperature of the body is very low. This condition is a medical emergency that occurs when the body loses more heat than what it is able to produce; hence, the body temperature decreases. The part of the brain called the hypothalamus is responsible for controlling body temperature; therefore, hypothermia is the result of the dysfunction of the hypothalamus. In order for a person to become hypothermic, their body temperature must be…
a stir plate to dissolve the compound and then a thermometer to measure both the initial and final temperatures of the compounds. Before we began our experiment it was necessary to look into the MSDS…
experiment was based heavily on the use of a variety of apparatuses including thermometers, water baths, beackers etc. and relies on the exactitude of this equipment to gain accurate results each time. It is possible that the water baths used to heat the thiosulfate solution were not working correctly i.e. a 40°C bath could not reach 40°C, usually this would not be an issue due to the temperature being monitored by a thermometer although if this apparatus was also not working properly it would…
and documented in that order. The order goes, temperature, pulse, respirations, and last blood pressure. Starting with the temperature, there is a tool called a tympanic digital ear thermometer. This is a way of measuring the body temperature inside the ear. It is the quickest way. The tympanic digital thermometer is a hand held device with a “window” showing…
was lower than the boiling point of acetone, the most volatile solvent possibly present in the unknown solution, pointing to a source of error in the measurement of the temperature. This could have been due to an inaccurate thermometer or to an error in placing the thermometer too high. Because the boiling point was so low, the more volatile solvent was estimated to be acetone, which has a boiling point of 56.5°C. After fraction A was collected, the temperature of the stillpot was increased…
set up of the experiment. The experiment is not a perfectly isolated system which could have lead to transfer of heat from the solution to the environment and vice versa. The thermometer used in the experiment could be inaccurate by a fraction of a degree and cause quite a difference in the calculations. Also when the thermometer is first…
The thermometer was immediately placed inside the water, and the temperature was measured and recorded as close to boiling point as possible. A ruler was then placed along the side of the measuring cylinder and the stretch length of the rubber band, between the skewer and the steel weight, was recorded. 6. The thermometer was left inside the measuring cylinder. When the water had dropped to 80 0C, the new stretch…
In part one the Styrofoam cups and the substances that are in the cup which is distilled water and sodium hydroxide was the system while the stir rod and thermometer and the Vernier unit is the surroundings. In part two the Styrofoam calorimeter, HCl and NaOH are the system while the stir bar and the tool that is used to measure the temperature is the surroundings. In part 3 HCl, Styrofoam cup calorimeter and NaOH are the system while the temperature probe, stirring rod are the soundings 6.)…
invention was a gargantuan step towards where humanity is today, there were yet other pieces of equipment to be made. The invention of the thermometer was also an example of a device made in the scientific revolution that aided many people. Galileo—the same Galileo that supported Copernicus’s heliocentric theory—was the creator of the earliest form of the thermometer, which was used for measuring the temperature of the environment it was placed in. This temperature-measuring tool was improved by…
