Surface Tension
What is a measure of how difficult it is to stretch or break the surface of the water?
|
Kinetic Energy
What is the energy of motion?
|
It Expands
When water freezes what happens to it?
|
Aqueous Solution
What is a solution where water is the solvent?
|
7
What is the PH of pure water?
|
|
Cohesion
What are the hydrogen bonds that make water more structured than other liquids called?
|
Heat
What is a measure of matter's total kinetic energy known as?
|
The water molecules slow down so they cant break their hydrogen bonds
What causes ice to expand when frozen?
|
A solution is a substance getting dissolved in a solvent in a mixture.
What is the difference between a solvent and a solution?
|
Acid
What is a substance that increases the hydrogen into a concentration of a solution?
|
|
Adhesion
What is the clinging of one substance to another?
|
Temperature
What is the measure of the average amount of energy in a molecule regardless of volume?
|
They would Freeze
If ice sunk what impact would that have on lakes?
|
It can dissolve more substances than any other liquid.
Why is water known as a universal solvent?
|
Base
What is a substance that decreases the hydrogen into a concentration of a solution?
|
|
Cohesion and Adhesion
The water adheres to the root wall and the water is pulled up through the cohesive bonds as water at the top of the tree is evaporated.
How is water able to go against gravity in the roots of a tree?
|
Specific Heat
What is the amount of heat that must be absorbed or lost to change 1g of water 1 degree Celcius?
|
10%
Home muck less dense if frozen water than liquid water?
|
Hydrophobic
What is a substance that is nonionic and nonpolar and seems to repel water known as?
|
Buffer
What is a substance that minimizes changes of H+ and OH- in a solution?
|
|
Cohesion is the bonding of one substance to other molecules of the same substance
Adhesion is the bonding of one substance to a different substance
Explain how cohesion and adhesion are different.
|
Heat of Vaporization
What is the amount of heat that a liquid must absorb of 1g of the substance to change from its liquid state to a gaseous state?
|
It Contracts
When water cools from 4°C to 1°C what happens to it?
|
Molecular Mass
What is the sum of all the masses of all the atoms in a molecule?
|
There is no set minumum
