A sample of krypton gas at 292 K and 0.354 atm occupies a volume of 2.18 L. If the pressure of the gas is increased, while at the same time it is cooled to a lower temperature, the final gas volume O could be larger or smaller than 2.18 L depending on the final pressure and temperature. O will be smaller than 2.18 L. will be larger than 2.18 L.

1. What are fibers and where are they found? How could forensic scientists use fibers to solve a crime?   2. Define the word probative. What is the probative value of a fiber in a forensic investigation?     3. Describe steps you would take from collecting a fiber(s) at a crime scene to performing an analysis to determine its identity.     4.  Which of the 6 fiber types you observed are natural? Which are man-made?     5.  Are fibers classified or individualized? Why?

Assume the data below was collected for two different sample solutions using the same experimental procedure you carried out. Based on the two lines shown below, which solution (orange data points or blue data points) corresponds to the sample that would look DARKER in terms of how much light goes through the glass. 0.9 y= 4.7713x - 0.0728 R0.99953 0.8 0.7 0.6 0.5 0.4 0.3 0.2 y1.414x - 0.0546 R0.99642 0.1 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.1 [Concentration, M] orange data points (lower line) blue data points (upper line) Absorbance

Sand and iron particles that are similar in size and color are mixed together in a beaker. What would be the best method of separating the particles? A- Add water to the mixture B- Use tweezers to separate them. C- Pour the mixture into a filter. Use a magnet to separate them.

Select ALL of the metals listed below. O hydrogen (H) calcium (Ca) O gold (Au) silicon (Si) iodine (1I) O uranium (U)

Each sketch below shows three objects with an electric charge. In each case, decide whether there is a net force acting on the object outlined in green. If there is a net force, decide whether it pushes the green-ring object to the left or right. Then select the appropriate button under the sketch. For example, if there is a net force pushing the green-ring object in the first sketch to the left, select the left button under the first sketch. If there is no net force on the green-ring object in the second sketch, select the middle button under the second sketch. And so on. ola -2 +3 -2 -2 I Don't Know Submit 2022 McGraw Hill LLC.
