What is adhesion?

• Water's ability to stick to itself
• Water's ability to stick to other substances
• The strength of the cohesion of all the water molecules combined
• Tape, glue and other adhesives

What is cohesion?

• Water's ability to stick to other water molecules

• Water's ability to stick to other substances
• The strength of the cohesion of all the water molecules combined
• Tape, glue and other adhesives

What is surface tension?

• Water's ability to stick to itself
• Water's ability to stick to other substances
• The strength of the cohesion of all the water molecules combined
• Tape, glue and other adhesives

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Capillary action pulls the water molecules like a chain
• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves

Attractions between water molecules are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

Water is polar because...

• The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
• The molecule has two poles, at which the it is colder than other regions of the molecule.
• The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.
• The water molecule is neutral.

Which types of compounds dissolve easily in water?

• Polar and Nonpolar
• Polar and Ionic
• Nonpolar and Ionic
• Covalent and Nonpolar
