Jeopardy Intermolecular Forces
You are always so rigid!
100 – What is a condensed state of matter?
A substance with a significantly higher density than in the other states
200 – Describe the volume and shape of solids.
They retain both their own volume and shape
300 – What property allows water to be carried from the root to the tip of a plant?
surface tension
400 – What is the smallest repeating pattern in a solid called?
unit cell
500- How can ionic solids be both brittle and hard at the same time?
The bonds are really strong when they are aligned correctly but if they get out of
alignment there is a large amount of repulsion.
Don’t be so forceful!
100 – Which is stronger, an intermolecular force or an intramolecular force?
intramolecular
200 – What are the three types of intermolecular forces?
dipole-dipole, hydrogen, and dispersion forces
300 – Why does water have an unusually high boiling point?
it is held together by H bonds.
400 – What type of intermolecular force is found in noble gases and why?
dispersion forces – they have induced dipoles which is the reason noble gases will
bond.
500 – How do intermolecular forces determine boiling points?
the stronger the intermolecular forces, the higher the boiling point.
Let’s flow into this category
100 – The resistance to flow is known as
viscosity
200 – Why can insects walk on water?
surface tension
300 – Why do oceans moderate the temperatures on the earth?
They are able to absorb and release large amount of heat without a temperature
change.
400 – What affect does an increase in temperature have on viscosity?
it reduces the viscosity
500 – What happens to the boiling point at high altitudes and why?
It decreases because the atmospheric pressure decreases so the vapor pressure
doesn’t have to be as high to meet the atm. pressure
What state am I in?
100 – The change from a solid to a liquid is known as
melting
200 – The description of a liquid that evaporates very easily
volatile
300 – Transformation from a solid directly to a gas
sublimation
400 – This change of state includes evaporation and boiling.
vaporization
500 – Give me an example of opposite changes of state.
vaporization and condensation, freezing and melting
Palmer’s Picks
100 – What is a molecule with 2 poles known as?
dipole
150 – What is the difference between freezing point and melting point?
They are the same
200 – Why is there water on the outside of a cold can on a hot day?
The cold can cools the air and the water vapor condenses and turns to water.
300 – What is an amorphous solid and give an example.
something that looks like a solid but does not behave like a solid. glass
400 – What is the principal feature of metallic bonds and why are metallic bonds useful
to us?
they share electrons and they make good conductors
500 – Explain dynamic equilibrium and tell me where it occurs.
it is when the change of state from liquid to gas and gas to liquid happens at a
constant rate and you can’t see the change. It happens in a closed container.
