Read the hypothesis below and identify the dependent variable:

If coal is used to heat a school building, then the amount of air pollution around the building will increase.

• Type of pollution

• Amount of air pollution

• Type of resources

• Amount of coal used

What is water called because it dissolves more substances than any other substance?

• the universal solvent

• supreme solvent

• the universal solute

• planetary ruler

Water is considered a polar molecule because it has -

• a slight positive charge on one end and a slight negative charge on the other.

• adhesion

• cohesion

• it has charges distributed throughout the molecule

Water molecules are attracted to other water molecules. What is this property of water called?

• adhesion

• cohesion

• surface tension

• capillary action

Water molecules are attracted to other polar molecules. What is this property of water called?

• cohesion

• adhesion

• capillary action

• surface tension

Which property of water is defined as the property of the surface of a liquid that allows it to resist an external force?

Hint: it is the property of water that allows this water strider to walk across the surface of water.

• capillary action

• density

• surface tension

• high specific heat

How does water dissolve so many other polar substances, like NaCl (salt)?

• it breaks apart the chemical bond holding the Na molecule to the Cl molecule then surrounds each

• it creates the chemical bond holding the Na molecule to the Cl molecule then surrounds each

• it surrounds the NaCl molecule and changes the density
