Concept explainers
(a)
Interpretation:
An equation for T (°F) in terms of R should be determined.
Concept introduction:
We have the equation for T as:
Since, the plot of temperature versus dial mark(R) gives a straight line, so the possible relation between T and R may be as per straight line:
Here, n is described as the slope of the straight line and the y-intercept is explained as K.
(b)
Interpretation:
The thermostat setting needed to obtain a temperature of 320°F should be determined.
Concept introduction:
We have the equation for T as:
Where, K value is 3.17 and n value is 1.184.
The thermostat setting can better be obtained by getting the value of the dial setting R.
(c)
Interpretation:
The several possible explanations related to value of R in part (b) should be determined.
Concept introduction:
The thermocouple is a type of thermometer which has an application in industries for measuring extreme temperatures.

- Match the units to the setup below for calculation of molarity X when dissolving a liquid X (X g)(density = D g X/mL X) in a liquid Y (Y mL)(density = D g Y/mL Y). All equations are set up so that the unit on the bottom cancels with the unit on the top to its immediate left. Be sure to match any unused answers to "Unused answer".

Another solution, containing 3 kilograms of dissolved salt per liter, runs into the tank at 4 liters every minute and that the mixture (kept uniform by stirring) runs out of the tank at the rate of 1 liter per minute. What is the concentration of the solution in the tank at point of overflow? Intermediate values should be rounded only to two decimal places.

Use (i) conversion factors from the table on the inside front cover and (ii) Equation 3.1-2.(b) a solid with a specific gravity of 5.7. What did you assume to come up with your answer?arrow_forwardA temperature scale that never quite caught on was formulated by the Austrian chemist Johann Sebastian Farblunget. The reference points on this scale were 0°FB, the temperature below which Farblunget's post nasal drip began to bother him, and 1,000°FB, the boiling point of beer. Conversions between °C and °FB can be accomplished with the expression T(°C) = 0.0940T (°FB) + 4 Louis Louis, Farblunget's French nephew attempted to follow in his uncle's footsteps by formulating his own temperature scale. He defined the degree Louie using as reference conditions the optimum serving temperature of marinated snails (100°L corresponding to 15°C) and the temperature at which the elastic in his briefs began to relax (1,000°L corresponding to 43°C). a) At what temperature in °R does beer boil? b) What is the temperature interval of 25 Farblunget degree equivalent to in °C, K, °F, and °R? c) Derive equations for T(°C) in terms of T(°L); and T(°L) in terms of T(°FB) d) Ethane has a boiling point of…arrow_forwardAnswer questions 1 and 2 according to the data given.

- An environmental study was performed to measure the transport of a DDT (a banned pesticide) throughout the globe. A lake in northern Canada was sampled to see if low levels of DDT were present there in spite of it not being administered within 1000 miles of that location. 1.000 L of the lake water was spiked with 100.0 uL of a 2.451 ug/L solution of tetrachlorobenzene, which acted as the internal standard. The entire 1.000 L spiked solution was concentrated onto an SPE column. After washing the SPE column with ~5 mL of pure water, the analyte and internal standard were eluted from the SPE column using ~5 mL of CH2Cl2 solvent. The eluted sample was evaporated under a stream of nitrogen to a final volume of 1.000 mL. 1 uL of this final solution was analyzed using GC-MS, and gave a signal of 24835 for DDT and 11597 for tetrachlorobenzene. To calculate the response factor, a standard solution was prepared consisting of 1.482 ug/L of DDT and 2.451 ug/L of tetrachlorobenzene.…arrow_forwardYou have been provided with data of 2 groundwater samples.

- EXAMPLE 3-4: MORE-COMPLEX UNIT CONVERSION Convert the density of iron from 7.874 g/cm³ into kg/m³. Solution g 7.874 (1000) (- 3 7 874000 kg 1kg) (100cm) = (²1000 m) = 7874 kg/m³ m³ 3 Notice in Example 3-4 that we needed three identical conversion factors to eliminate the cm³. We also placed cm in the numerator of the conversion factor because cm³ was in the denominator of the measure- ment.
