- Perform the following pressure conversions, assuming when necessary that atmospheric pressure is 1 atm. Unless otherwise stated, the given pressures are absolute.

What is the temperature in C and K ?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…
- Here in this PV=nRT problem, I solve for the temperature in C. 800 mm Hg / 760 mm Hg = 1.052631579atm. Chlorine gas is cl2, 100g/70.9g=1.410437236. After algebra, I get 227.211655.

- In our chemistry laboratory class, the formula for surface tension given is y=mg/2(pi) x r x f where y=surface tension, m= mass of the drop, g= gravitational acceleration, pi is 3.1415, r= outer radius of burette, f=correction factor. Now I searched the internet and it says that the unit for surface tension is kg x m/s^2. The problem is I have grams for the mass of the drop and that the outer radius of the burette is in centimeter while the gravitational acceleration is in meter. What will happen is like this: (1 g x 9.8 m/s^2) / 2 (3.1415) x 0.15 cm x 0.74643 (correction factor no unit) As you can see, if I don't cancel m and cm, the unit will be g x cm x m x s^2. However if change the radius of the burette into meter, it will cancel, the unit will be g x s^2 (missing meter). What can I do to get kg x m/s^2 as the unit for final answer?11. The following question is from a practice website. It is shown in the photo below.Based on the charles' law, the following errors in procedure will affect the experimental result. Explain how wach action causes an incorrect result. Procedure(part A) 1) Student A was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing. 2) Student B used the measurement of Flask no. 1 to be 250mL, without measuring the volume directed. 3) Student C recorded the temperature in degrees Celcius and used these values in calculations. Procedure(part B) 4) Water remained on the outside of the flask and on the foil when the final mass was determined.
