Which of the following statements are correct concerning the scientific method? There is more than one correct answer. "When a can of soda pop is opened, a fizzing sound is heard." This is an example of observation. A scientific theory eventually becomes a law "Helium balloons float because helium is less dense than air." This statement can be considered an observation. Scientific law is a tentative interpretation or explanation. Both scientific law and theory have the potential to be proven wrong.

Suppose the densities of two metals are so close together that density is difficult to use to be able to distinguish them within the margin of error (a good example would be zinc and tin). What other physical properties could you use to determine which metal was which? Explain your reasoning thoroughly.

Part 2: Intensive vs. Extensive Properties. Compare the matter. Do they have the same extensive property or the same intensive property? Extensive properties define a quantity. Intensive properties define unique characteristics because of composition. On the line next to the item, • type I for intensive only • type E for extensive only • type B for both if there are common intensive and extensive properties type N for neither if there is no common intensive or extensive property. • Only type the letter. 13 14 15 16 17 18 19 20 21 22 A 10 kg granite rock and a 10 kg basalt rock. 50 liters of water and 20 liters of water. 40 grams of chalk and 30 grams of chalk. 1 kg basketball and 0.10 kg golf ball. 10 liters of hydrogen gas and 10 kg of air. 20 meters of rope and 20 meters of string. 50 grams of clear glass and 30 grams of clear plastic 100 kg human and 50 kg tree. 2 kg polyethylene helmet and 1 kg polyethylene knee pads 40 pounds of zinc and 40 pounds of iron.

1. A hollow square metal tube has a measurement of 2.42 in for each side and a weight of 53.71 g. The volume of empty space inside the tube was measured to be 0.93 in3. If the density of the metal used in constructing the tube is 11.81 g/mL, calculate the length of the tube in inches. 2. Porosity is a measure of the void or empty spaces in a material and is a fraction of the volume of voids over the total volume. The density of the solid material used to create 6 pieces of 0.99 cm diameter and 1.17 cm height cylindrical beads is determined to be 1.84 g/mL. These beads were then placed in a flask and were filled to the 43 mL mark with a salt solution. The total weight measured of the beads and the salt solution was 47.22 g. Upon further inspection, it was found that manufacturing defects caused the measured porosity of the beads to be at 20%. Assuming that the solution was able to fully fill the empty spaces inside the beads, calculate the density of the salt solution. 3. A chocolate…
