Polarity & Properties of Water | BOGO Biology Flashcard

Front

What shape does a water molecule resemble?

Back

V-shaped

Front

What causes water molecules to have a dipole moment?

Back

Unequal electron sharing due to electronegativity differences

Front

How many hydrogen bonds can one water molecule form at a time?

Back

4

Front

Why does water have a high specific heat capacity?

Back

Due to the hydrogen bonds it forms

Front

What property of water helps in maintaining homeostasis in living organisms?

Back

Specific heat capacity

Front

What allows insects to walk on water? Options: High specific heat capacity, Adhesion to water molecules, Surface tension due to cohesion, Capillary action

Back

Surface tension due to cohesion

Front

What phenomenon causes water to form a rounded bead on waxy surfaces?

Back

Both cohesion and adhesion

Front

What is necessary for capillary action to occur?

Back

Adhesion being stronger than cohesion

Front

How does capillary action benefit plants?

Back

It allows water to move upwards against gravity.

Front

What role does capillary action play in medical diagnostics?

Back

It is used to measure blood sugar levels
