Read each question carefully and provide your best answer. Some questions may require short explanations or definitions. For multiple-choice questions, select the best option.
1. What property of water allows insects to walk on its surface?
High specific heat capacity
Surface tension
Adhesion
Low density as a solid
2. Which type of bonding is responsible for many of water's unique properties?
Ionic bonding
Covalent bonding
Hydrogen bonding
Metallic bonding
1. Water is a molecule due to the uneven sharing of electrons between oxygen and hydrogen atoms.
2. The property of water that allows it to stick to other surfaces is called .
3. Ice floats on water because it is less than liquid water.
1. Explain why water has a high specific heat capacity and describe its importance for living organisms.
2. Describe the concept of 'cohesion' in water and provide an example of its effect.
Observe the diagram of a water molecule below and answer the question.
1. Based on the diagram, explain why the oxygen atom in a water molecule has a partial negative charge and the hydrogen atoms have partial positive charges.
1. Water molecules are nonpolar.
True
False
2. Capillary action is a result of both cohesion and adhesion.
True
False
