What property allows water to stick to wax paper and keep its water drop form?
Adhesion
400
How does temperature affect viscosity?
Increase in temp causes viscosity to increase (liquids will flow slower)

What is the phase change called when you have a substance that has an indefinite shape and definite volume to a substance that has a definite volume and definite shape?
Freezing
400
What letter represents a point where you will see molecules in the liquid state and molecules in the gas state?
D
400
A sample of gas has a volume of 30 mL at a temperature of 273 K. If the temperature is changed to 200 K, what is the new volume?
~22 mL

What movie series am I obsessed with?
Star Wars!

Explain how certain insects can walk on water.
These insects use the property of surface tension which is when water creates a film at the surface. This film allows certain insects to walk on it

What is the phase change called when you to from molecules that are able to flow past each other to molecules that are moving rapidly?
Boiling
500
If this was a cooling curve, what would the phase change at point D be called?
Condensation Point
500
A sample of gas occupies 250 mL at 1.00 atm of pressure. If the pressure increases to 2.00 atm, what is the new volume?
125 mL

DOUBLE JEOPARDY!!! Explain how water is less dense as a solid than it is as a liquid.
Water will expand as it freezes into ice which will then cause the volume to increase but the base remains the same. Based on the density equation (D = M/V), the density will then decrease.
