Describe how surface area, temperature, and intermolecular forces are related to the rate of evaporation of a liq

Learning Goal: I’m working on a chemistry question and need an explanation and answer to help me learn.

  1. Question 1

    1 PointDescribe how surface area, temperature, and intermolecular forces are related to the rate of evaporation of a liquid and vapor pressure.

  2. Question 2

    1 PointWhat are the 3 interactions that happens in a solution between the solute and the solvents? Describe the interactions in terms of salt dissolved in water.

  3. Question 3

    1 PointWhy can’t the kinetic molecular theory be applied to liquids and solids?

  4. Question 4

    1 PointIdentify which of these gases exhibit non-ideal gas behavior:Gas A, Gas B, Gas C, Gas D, Gas E, Gas F

  5. Question 5

    1 PointDescribe the 4 standards that gases need to have in order to fit the kinetic molecular theory of gases.

  6. Question 6

    1 PointA box contains 100 particles of gas at room temperature. The temperature of the box is increased. How does the motion of the particle change and affect pressure?

  7. Question 7

    1 PointYou are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. You are checking the purity of the air in a unit of the hospital and find the following readings: CO2 (17.8 Pa), O2 (20.2 bar), CO (56.6 psi), N2 (71.7 mmHg), SO2 (22.4 torr), and Ar (42.3 atm). What is the total pressure of the unit?

  8. Question 8

    1 PointYou are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. Patient C needs oxygen administered due to difficulty breathing. Check how many mols of gas is in a cylinder that has a volume of 5L at 13700 kPa, at atmospheric pressure and room temperature at 20 degrees Celsius.

  9. Question 9

    1 PointYou are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. A scuba diver has been brought into the hospital because he had to come up really quickly since his oxygen tank was running out. The problem with doing this is that it causes a phenomenon called “bends” where the volume of the oxygen in the blood stream can increase too quickly if the pressure around the body is changed too quickly. If the scuba diver had 4.0 L of gas at atmospheric pressure, what was the volume of the gas when scuba diver dove down to 130ft below sea level (110kPa)?

  10. Question 10

    1 PointYou are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. The hospital just received a shipment of helium gases at various purities. A helium tank with a purity of 95% has helium (11.6 mmHg), nitrogen (2.8atm), and oxygen (4.3 kPa). What is the total pressure of the tank?

  11. Question 11

    1 PointIn a gaseous state, molecules can be compressed.

  12. Question 12

    1 PointIn a liquid state, molecules can be compressed.

  13. Question 13

    1 PointWhich of these examples are liquids of low viscosity?

  14. Question 14

    1 PointWhich of these examples are liquids of high viscosity?

  15. Question 15

    1 PointUsing the phase diagram, identify the phase that water is in for the following conditions: 22,089kPa and 374˚CDiagramDescription automatically generated

  16. Question 16

    1 PointUsing the phase diagram, identify the phase that water is in for the following conditions: 100kPa and 110˚CDiagramDescription automatically generated

  17. Question 17

    1 PointIdentify which of these molecules has the highest boiling point and give the reasoning why in terms of intermolecular force. CHCl3, H2O, CO2

  18. Question 18

    1 PointIdentify which of these molecules has the highest boiling point and give the reasoning why in terms of intermolecular force. CHCl3, CH3COOH, CO2

  19. Question 19

    dentify the following phase change as endothermic or exothermic processes: Gas to liquid

  20. Question 20

    Identify the following phase change as endothermic or exothermic processes: Liquid to solid

  21. Question 21
  22. Reference this image and identify whether the following solution is saturated, supersaturated or undersaturated: KBr at a solubility of 60 at 20˚C
  23. Question 22

    Reference this image and identify whether the following solution is saturated, supersaturated or undersaturated: Sugar at a solubility of 220 at 30˚C

  24. Question 23

    Calculate the molality of the following solution: 37g of glucose (C6H12O6 ) in 64g of water

  25. Question 24

    Calculate the molality of the following solution: 4.2g of LiBr in 52.6g of water

  26. Question 25

    Calculate the molality of the following solution: 30g of NaCl in 350g of water

  29. Question 28

    Calculate the mass percent of the following solution: 37g of glucose in 64g of water

  30. Question 29

    Osmotic drug delivery is a technique used in the pharmaceutical industry to help an active drug dissolve when swallowed. There are holes that are drilled onto the outside of the tablet allowing for the phenomenon to occur. With your knowledge of how osmotic pressure works, hypothesize what you think happens when a drug is ingested into the body
