Not so dry flashcard

Front

What makes water molecules stick together?

Back

Water molecules have one end with a slight negative charge and the other end with a slight positive charge, which causes them to attract each other.

Front

What happens when you rub a balloon on your hair?

Back

It creates electrostatic charges, allowing the balloon to stick to a wall.

Front

Why are water molecules considered 'sticky'?

Back

Water molecules are attracted to each other and to other surfaces.

Front

Why can't we see individual water molecules?

Back

They are incredibly tiny, even for powerful microscopes.

Front

What is electrostatic charge?

Back

An electrostatic charge is a physical property of matter that causes it to experience a force when placed in an electric field.

Front

What is the significance of positive and negative charges in molecules?

Back

Positive and negative charges in molecules lead to attractions that can affect the properties of substances, like water.

Front

How do water molecules behave in a group?

Back

They tend to stick together due to their polar nature, forming hydrogen bonds.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a weak attraction between a hydrogen atom and an electronegative atom, like oxygen in water.

Front

What is the role of water in nature?

Back

Water is essential for life, acting as a solvent, temperature regulator, and participant in chemical reactions.

Front

What is cohesion in water?

Back

Cohesion is the attraction between water molecules, which helps them stick together.
