COMPLETE SOLUTION with given and required ASAP You will be defining a new temperature scale in oX, in which the freezing and boiling points of water areone-hundred degrees X and one-thousand fifty-five oX, respectively. Correlate this to Celsius orFahrenheit scales. The oX reading on this scale is a certain number of degrees on a correspondingabsolute temperature scale. What is the corresponding absolute temperature at 0oX?

A study is being performed to see if there is a correlation between the concentration of chromium in the blood and a suspected disease. Blood samples from a group of volunteers with history of the disease are analyzed and compared with the results from the healthy control subjects. From the following results (Table 1), determine whether the differences between the two groups can be ascribed as chance or whether they are real at 95% confident level.
a Table: (This is an example of what your data table should look like.) Pressure (kPa) Temperature (°C) Temperature (K) Constant, k(P / T or P•T) Ice water bath 91.58 2.4 275.55 Room temperature 96.54 21.1 294.25 Warm water 104.11 44.5 317.65 Boiling water 113.75 77.5 350.5 Calculations: One way to determine if a relationship is inverse or direct is to find a proportionality constant, k, from the data. If this relationship is direct, k = P/T. If it is inverse, k = P•T. Choose one of these formulas and calculate k for the pairs in your data table (divide or multiply the P and T values). Record the answers in the fourth column of the Data table. How constant were the values for k you obtained in Question 4? Good data may show some minor variation, but the values for k should be relatively constant. Comment on your calculated k values. Analysis Questions: What does temperature measure? Look at your graph. What type…

A partially filled one-gallon [gal] pitcher, that has a mass of 0.35 kilograms [kg] when empty, is sitting on a kitchen counter. Assume the total mass of the pitcher and its contents is 2 kilograms [kg]. The pitcher contains a liquid that has a molecular weight of 19.5 grams per mole [(g)/(mol)] and a molarity of 57 moles per liter [(mol)/(L)]. (a) Determine the volume of the liquid in the pitcher in units of liters [L]. (b) Determine the specific gravity of the liquid in the pitcher.
