Find the total pressure of 3 gasses: Nitrogen has 200 mmHg, Oxygen has 100 mmHg, Fluorine has 50 mmHg
200 mmHg
100 mmHg
50 mmHg
101.3 kPa
350 mmHg
Which is stronger:
Intermolecular Forces
Intramolecular Forces
Stronger intermolecular forces cause viscosity to:
Increase (flow is reduced)
Stay the same (flow does not change)
Decrease (flow increases)
Water has a higher boiling point than propane. Why?
Intramolecular forces are stronger in water
Intramolecular forces are weaker in water
Intermolecular forces are stronger in water
Intermolecular forces are weaker in water
Which is not a property of solids?
Definite Volume
Fluid
Definite Shape
Incompressible
Which is not an assumption of the Kinetic Molecular Theory?
Particles are always in very fast, random motion
Particles move in a straight line until they collide with something
Collisions are elastic (no kinetic energy is lost)
Gas Particles are far apart
All of the above are assumptions of Kinetic Molecular Theory
Hydrogen Bonds occur between Hydrogen and
Iodine
Fluorine
Oxygen
Chlorine
Nitrogen
Which property of liquids allows a leaf to float on water?
Surface Tension
Viscosity
Boiling Point
Intramolecular forces
The triple point of a substance is best characterized by:
Being three types of solids
It is the only time you can use a triple beam balance
Solid, Liquid and Gas states are all present
It is not special .
Stronger Intermolecular forces would cause which of the following?
A lower boiling point
Slower evaporation
Greater surface tension
Decreased Viscosity
Select the molecule that would result in dispersion bonds
Which of the following would result in Dipole-Dipole bonds?
Which of the following will form Hydrogen Bonds?
Which will have a higher melting point?
Why are gases more compressible than liquids or solids?
Gases have more space between particles
Liquids and solids have more space between particles
Gases are more dense than liquids and solids
Gases are just squishy
Select the gas that will diffuse most quickly
CO2 (Molar Mass = 44 g/mol)
CH4 (Molar Mass = 16 g/mol)
O2 (Molar Mass = 32 g/mol)
Ne (Molar Mass = 20 g/mol)
The "normal" phase change points occur at
5 atm of pressure
Pressure does not matter for phase changes
1 atm of pressure
3 atm of pressure
Vaporization will occur when
Vapor pressure is lower than atmospheris pressure
Vapor pressure is greater than atmospheric pressure
When the temperature is above 0 degrees Celsius
