Answer the following question given this paragraph: Both temperature and pressure have an effect on the phase in which a given substance exists. A plot of temperature vs. pressure that indicates the states of matter present at each point is known as a phase diagram . Figure below shows the phase diagram for water. Q: A phase diagram plots temperature and what else? Choices: - friction - power - movement - pressure A:
pressure
Answer the following question given this paragraph: The folded surfaces of the gills provide a large surface area to ensure that the fish gets sufficient oxygen. Diffusion is a process in which material travels from regions of high concentration to low concentration until equilibrium is reached. In this case, blood with a low concentration of oxygen molecules circulates through the gills. The concentration of oxygen molecules in water is higher than the concentration of oxygen molecules in gills. As a result, oxygen molecules diffuse from water (high concentration) to blood (low concentration), as shown in Figure 39.5. Similarly, carbon dioxide molecules in the blood diffuse from the blood (high concentration) to water (low concentration). Q: What term is used to describe a process in which material travels from regions of high concentration to low concentration until equilibrium is reached? Choices: - fission - active transport - Osmosis - diffusion A:
diffusion
Q: Answer the following question given this paragraph: An atomic orbital is a region of space around an atom that has a non-zero probability for an electron with a particular energy. Analogously, a molecular orbital is a region of space in a molecule that has a non-zero probability for an electron with a particular energy. Both an atomic orbital and a molecular orbital can contain two electrons. Q: What term describes a region of space around an atom that has a non-zero probability for an electron with a particular energy? Choices: - orbital lobe - minimal orbital - related orbital - atomic orbital A:
A: atomic orbital
Question: Answer the following question given this paragraph: An addition polymer is a polymer formed by chain addition reactions between monomers that contain a double bond. Molecules of ethene can polymerize with each other under the right conditions to form the polymer called polyethylene. Q: What is a polymer formed by chain addition reactions between monomers that contain a double bond called? Choices: - a linear polymer - a branched polymer - an addition monolayer - an addition polymer A:
Answer: an addition polymer
