Modern Day Temperature Measurement Devises And Their Uses

The water was taken from the same source and the same thermometer was used, yet different values were derived each time. This is a type of environmental factor, which is a random error as it affected the values differently.

Step 3: Use the thermometer to identify and record the temperature for room temperature, in your refrigerator, in your freezer, and then research the temperature of boiling water (do not take this temperature) and record them in Table 2.

Using a thermometer we observed the measurement of the water “H2O” in the beaker, and it resulted in an initial temperature of 20 ⁰ C.

29. When the thermometer reads 40°C, carry the beaker out of the heating apparatus with a beaker tong.

Calorimetry is the science of measuring the change in heat absorbed or released during a chemical reaction. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. The device used to measure calorimetry is a calorimeter. A calorimeter can range from very expensive lab ones to coffee styrofoam cups but they are all tightly sealed in order to prevent heat from escaping.

    One possible source of error that can affect the results was that a mercury thermometer was used instead of an electronic one. The use of a mercury

A scale conversion is calculated and the measurements from each thermometer are examined to see how closely correlated they are. _M___

9) Trial E: Remove the syringe and empty the beaker. Add a Thermometer to the beaker. Add 200 mL of Room Temperature water to the beaker and heat with a Bunsen Burner until it reaches 100° C. Remove the Bunsen Burner. Repeat Steps 5 & 6.

Frost forms when there is enough moisture in the air and the ground is cold to

The room temperature was measured throughout the lab and kept constant at 24°C (+/- 1°C), as the lab was conducted during the same time of

The Materials that were used to measure the experiment where a pen and paper to record the reactions of the subjects being tested, and the subjects themselves.

For Part B of the experiment, begin by placing a Styrofoam cups into another and then the two into a 400 mL sized beaker. Pour 50 mL of 2M HCl into the top Styrofoam cup. Then, place the lid over the cup and stick the probe into the cup. Obtain 50 mL 2 M NaOH using a graduated cylinder. Begin by collecting 3-4 initial temperature readings using LabQuest. Then pour the

What Galileo needed was to come up with some sort of device that could make him a tidy profit. A rudimentary thermometer (which, for the first time, allowed temperature variations to be measured) and an ingenious device to raise water from aquifers found no market. He found greater success in 1596 with a military compass that could be used to accurately aim cannonballs. A modified civilian version that could be used for land surveying came out in 1597, and ended up earning a fair amount of money for Galileo. It helped his profit margin that 1) the instruments were sold for three times the cost of manufacture, 2) he also offered classes on how to use the instrument, and 3) the actual toolmaker was paid dirt-poor wages.

To achieve this, the final value from each thermocouple was set to be equal to the warm water bath temperature (370C), and the initial reading was set equal to the ice water bath temperature. Thus, for each thermocouple an equation was obtained using the two points to convert voltage readings to temperature. An example of the calibration for one of the thermocouples is shown in Appendix II.

Rinse the thermometer with tap water and dry. Insert the thermometer in the calorimeters top and measure the initial temperature of the base 28.2∘C
