Properties of Water and Carbon

Front

What characteristic of water allows a paperclip to remain floating on the surface of water?

Back

Surface tension is the property of water that allows a paperclip to float on its surface.

Front

Which end of the water molecule has a slightly positive charge?

Back

The hydrogen end of the water molecule has a slightly positive charge.

Front

What is a molecule in which opposite ends have opposite electric charges called?

Back

A polar molecule.

Front

What is capillary action?

Back

Capillary action is the ability of water to move up a thin tube against gravity, due to adhesion and cohesion.

Front

Why is water considered a universal solvent?

Back

Water is considered a universal solvent because it can dissolve most substances.

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules to each other.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and release large amounts of heat without significant temperature changes, stabilizing climates.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds are weak attractions between the hydrogen atom of one water molecule and the oxygen atom of another, contributing to water's unique properties.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, allowing ice to float.
