Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.
Q1
Use kinetic molecular theory to explain the origin of gas pressure.
Q2
Convert the following Pressures:
- 600 mm Hg into atm
- 190 kPa into atm
- 2.3 atm into mm Hg
- 1.5 atm into kPa
Q3
Use kinetic molecular theory to relate (translational) kinetic energy to temperature.
Q4
What is the temperature at absolute zero
Q5
Use kinetic molecular theory to explain the difference between evaporation and boiling of a liquid.
Q6
Use the chart to answer the following questions.
- What is the vapor pressure of ether at 40ºC?
- What is normal boiling point of water?
- What is the normal boiling point of benzene?
Q7
How is the average kinetic energy of water molecules affected when you pour hot water from a kettle into cups at the same temperature as the water?
Q8
What is the relationship between atmospheric pressure and altitude? What effect does this have on the boiling point of water?
Q9
Define vapor pressure.
the pressure of the vapor over a liquid at equilibrium (meaning that as many molecules are going into the vapor state as there are gas molecules going back into the liquid state) this is measured in a closed container.
Q10
What is the definition of the boiling point of a liquid?
Q11
Explain why the boiling point of a liquid varies with atmospheric pressure.
Q12
Using the diagram above: What would happen to the CO2 if you:
- Heat it up from -60º to 30º C at 6.0 atm?
- Increase the pressure from 2.0 atm to 60 atm at a temperature of 0ºC?
- Decrease the pressure from 80.0 atm to 1 atm at a temperature of 25ºC?
- Increase the temperature from -80ºC to +80ºC at a pressure of 1.0 atm?
- Increase the temperature from -60ºC to 20ºC at a pressure of 70 atm?
