RC Chemistry Surface Area Temperature & Intermolecular Forces Practice Quiz

Question 1 Describe how surface area, temperature, and intermolecular forces are related to the rate of evaporation of a liquid and vapor pressure. Question 2 What 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.Question 3 Why can’t the kinetic molecular theory be applied to liquids and solids?Question 4 Identify which of these gases exhibit non-ideal gas behavior:Gas BGas AGas CGas D Gas EGas FQuestion 5 Describe the 4 standards that gases need to have in order to fit the kinetic molecular theory of gases.Question 6 A 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?Question 7 You 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?Question 8 You 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.Question 9 You 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)?Question 10 You 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?Question 11 In a gaseous state, molecules can be compressed.TrueFalseQuestion 12 In a liquid state, molecules can be compressed.TrueFalseQuestion 13 Which of these examples are liquids of low viscosity?Motor oil, maple syrup, honeyMercury, water, glycerinWater, alcohol, gasolineRubbing alcohol, acetone, Butane, PropaneQuestion 14 Which of these examples are liquids of high viscosity?Rubbing alcohol, acetone, Butane, PropaneWater, alcohol, gasolineChloroform, sugar water, HCIMotor oil, maple syrup, honeyQuestion 15 Using the phase diagram, identify the phase that water is in for the following conditions: 22,089kPa and 374?CSolidLiquidCritical pointGasTriple pointQuestion 16 Using the phase diagram, identify the phase that water is in for the following conditions: 100kPa and 110?CGasLiquidCritical pointSolidTriple pointQuestion 171 PointIdentify which of these molecules has the highest boiling point and give the reasoning why in terms of intermolecular force.
