Water

The scientist is probably trying to answer what question with the investigation?

• Which temperature of water will allow water to dissolve the fastest?

• What substances can water dissolve?

What is known as the "universal solvent?"

• grape juice

• lemonade

• hydrogen

• water

Water is known as the "universal solvent" because _____________________.

• it is located everywhere

• many different kinds of substances can dissolve in water

• it can be a solid, liquid, or a gas

Ice cubes are less dense than liquid water.

• True
• False

Water has many unique properties:

• Adhesion

• Cohesion

• Dissolves other substances

  Why?

• Amount of energy

• structure

• states of matter

• heat

This is an example of -

• cohesion

• adhesion

• density

• surface tension

This is an example of -

(Hint: water sticks to itself)

• cohesion

• adhesion

• density

• surface tension

This is an example of -

(Hint: paper clip is resting on top of the water)

• cohesion

• adhesion

• density

• surface tension

This is an example of -

(Hint: Ice is floating in water)

• cohesion

• adhesion

• density

• surface tension

If you increase the thermal energy of water, it also ____________ the temperature of the water.
