What is density?

Why is ice less dense than liquid water?

Why is it important to ecosystems that ice floats in liquid water?

Why is water considered to be a universal solvent?

What is being measured in pH?

What is the range of the pH scale?

What is the pH of water?

What types of substance have pH values less than 7?

What types of substance have pH values greater than 7?

Give an example of a substance with a high concentration of H+ ions.

Give an example of a substance with a low concentration of H+ ions.

What is specific heat?

Does water have a high specific heat? What does this mean?

In the specific heat example, which liquid has the highest specific heat? (Remember that the more heat it takes to make the liquid raise 1 degree in temperature, the higher the specific heat it has.)

What is heat of vaporization?

Does water have a high heat of vaporization?

Define vaporize.

 

Why does water have a high boiling point?

 

Explanation:

Why is ice less dense than liquid water?

hydrogen bonds causes molecules to push farther apart, which lowers the density

Why is it important to ecosystems that ice floats in liquid water?

This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive. If ice sank, the liquid water on top would also freeze and sink, until all the liquid water became frozen.

Why is water considered to be a universal solvent?

water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth. ... This allows the water molecule to become attracted to many other different types of molecules.(Meaning water is the key to many diffrent types of molicules)

What is being measured in pH?

pH is a measure of how acidic/basic water is. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

What is the range of the pH scale?

The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

What is the pH of water?

What types of substance have pH values less than 7?

Pure water has a neutral pH of 7

What types of substance have pH values greater than 7?

hydrogen(I think)

Give an example of a substance with a high concentration of H+ ions.

(I dont know but if u try asking a teacher it might be mor helpfull

Give an example of a substance with a low concentration of H+ ions.

(also unkown ask a teacher  if you can)

What is specific heat?

Does water have a high specific heat? What does this mean?

Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.

In the specific heat example, which liquid has the highest specific heat? (Remember that the more heat it takes to make the liquid raise 1 degree in temperature, the higher the specific heat it has.)

Water

What is heat of vaporization?

is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.

Does water have a high heat of vaporization?

Water also has a high heat of vaporization, the amount of energy required to change one gram of a liquid substance to a gas

Define vaporize.

 convert or be converted into vapor.transition from the liquid phase to vapor.

Why does water have a high boiling point?

The reason for the high melting and boiling temperatures is the hydrogen bonding between water molecules that causes them to stick together and to resist being pulled apart which is what happens when ice melts and water boils to become a gas.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
