Answer:
C.
The pan will be the same temperature as the stove.
Explanation:
Because density=mass/volume, the density of a substance would increase if the mass was increased and the volume was not, and decreased if the volume was increased and the mass was not.
The answer is B, distillation.
(You can see more details about distillation as well as other separation techniques on the document pdf titled Lab #2 Physical Separation Techniques by ccri.edu)
To solve this problem we use Boyle's law to correlate the varying volume and pressure at constant temperature. Assuming ideal gas law, we use the equation P1/V1= P2/V2. Substituting, 735 mm Hg/ P2= 63.5 ml/69.2 ml. P2 is equivalent thus to 800.97 mm Hg.
Answer: Velocity
Explanation:
The density of a material affects the speed that a wave will be transmitted through it. In general, the denser the transparent material, the more slowly light travels through it. Glass is denser than air, so a light ray passing from air into glass slows down.
