Vaporization occurs more readily with: increased temperature, increased surface area, decreased intermolecular forces decreased temperature, decreased...
Action potential will propagate more readily in : A) axons with larger diameter vs axons with smaller diameter due to increased surface area B) in axons with smaller diameters vs axons with larger diameters due to decreased surface area C) axons that have been cooked
The size/shape advantage between prokaryotes and eukaryotes includes a) More surface area for increased nutrient uptake b) Larger cells are more difficult to phagocytose c) Decreased surface area allows for increased nutrient uptake d) Both A and B e) Both B and C
Think about intermolecular forces and the stronger the intermolecular force the more energy needed to separate the molecules. Just thinking about this, put the properties below in the correct category. Hints: Vapor pressure is high if it is easy for molecules to escape from a liquid into the gas phase. High surface tension means the liquid molecules do not separate easily Viscosity is the "thickness" of a liquid substance Strong intermolecular forces Weak intermolecular forces Answer Bank high boiling point...
1. solids, liquids, and solutions, and intermolecular forces. 1. For each pair of substances, identify which has the highest melting point. For each, briefly explain your reasoning Ne: e. Surface area also matters. More surface area, more contact, stronger cohesion. Your book mentions this. Based on that, which do you think is most likely to be a solid at room temperature?
Gas Behavior and Intermolecular Forces 1. The pressure exerted by a gas in a container is due to the collisions of the gas particles with the walls of a container. The illustration depicts a gas in a container with a movable piston. Consider each of the following changes and determine how the gas pressure will be affected. Your answer should indicate whether the pressure is increased, decreased or not changed. You should also provide an explanation. A The piston is...
What process occurs when the temperature of a substance is at Point A increased (at constant pressure) until the substance is at Point B? A. 1 B. sublimation freezing melting vaporization condensation
If the surface area of a cube is increased by a factor of 2 (so that the new surface area is twice the size of the original surface area), by what factor does the volume of the cube change?
If the surface area of a sphere is increased by 50.9%, its volume will most likely be increased by how much?
Question 3 (4 points) The vapor pressure of a liquid is dependent on: the temperature of the liquid and intermolecular forces of attraction in the liquid the temperature of the liquid and the surface area of the liquid only on the surface area of the liquid only the temperature of the liquid O only the forces of intermolecular attraction in the liquid Question 4 (4 points) If the atmospheric pressure over a sample of liquid is increased, the boiling point...
2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
