Approximately what is human body temperature on the Celsius temperaturescale and on the Kelvin scale? What is room temperature?2. Why must a thermometer be calibrated? You have a glass bulb thermometerwith no markings on it and a second one marked in degrees Celsius. Explainhow you would calibrate the unmarked thermometer. In order to Calibrate athermometer, the bulb is made to reach thermal equilibriumwith the temperature standard such as ice and thenwith another, standard 5uch as water or vapor and thentybę divided in to regular intervals between Axed point.abe isthe length of time it takés the temperature probe to reach therma'equilibrium with the air or water it is in.

1-87 Water that contains deuterium rather than ordinary hydrogen (see Section 2-4D) is called heavy water. The specific heat of heavy water at 25oC is 4.2 17 J/g oC. Which requires more energy to raise the temperature of 10.0 g by 10oC, water or heavy water?
1-86 The specific heats of some elements at 25oC are as follows: aluminum = 0.215 cal/g · oC; carbon (graphite) = 0.170 caI/g oC; iron = 0.107 cal/g mercury = 0.033 1 caI/g oC. (a) Which element would require the smallest amount of heat to raise the temperature of 100 g of the element by 10oC? (b) If the same amount of heat needed to raise the temperature of 1 g of aluminum by 25oC were applied to 1 g of mercury, by how many degrees would its temperature be raised? (c) If a certain amount of heat is used to raise the temperature of 1.6 g of iron by 10oC, the temperature of 1 g of which element would also be raised by 10oC, using the same amount of heat?

O Macmillan Learning One important test for kidney disease involves measuring the levels of bicarbonate (HCO,) in blood. Normal bicarbonate levels for a person ranging in age from 18 to 59 years old is 23-29 mmol/L. A lab purchased a new instrument to measure bicarbonate levels in blood and needs to certify it against their current instrument. The bicarbonate levels in the blood of a 38 year old woman was measured using the old and new instrument. The blood was tested 6 times using each instrument. The mean concentration of bicarbonate using the old instrument was found to be 24.4 mmol/L. with a standard deviation of 1.54 mmol/L. The new instrument yielded a mean concentration of 25.5 mmol/L with a standard deviation of 0.48 mmol/L... Determine if there is a significant difference in the standard deviations of the two sets of measurements made by the two instruments at the 95% confidence level.
