HOMEWORK #1: Properties of Water

Front

What is the property of water that allows it to dissolve many substances?

Back

Polarity

Front

Why is water often referred to as the 'universal solvent'?

Back

Because it dissolves most substances.

Front

What happens to the density of water when it freezes?

Back

Ice is less dense than liquid water, allowing it to float.

Front

What is capillary action in relation to water movement in plants?

Back

Capillary action pulls water molecules upward through the plant like a chain.

Front

How does water's cohesion affect its properties?

Back

Cohesion causes water molecules to stick together, which is important for processes like transpiration.

Front

What role does water play in maintaining homeostasis in the human body?

Back

Water helps remove waste from cells and transport nutrients.

Front

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

Back

It allows water to absorb and retain heat, stabilizing temperatures in the environment.

Front

How does the polarity of water contribute to its solvent properties?

Back

The polar nature of water molecules allows them to surround and interact with various solutes.

Front

What is the effect of water's hydrogen bonds on its physical state?

Back

Hydrogen bonds cause water to expand when it freezes, creating a solid that is less dense.

Front

Why do ice cubes float in a drink?

Back

Because ice is less dense than liquid water due to the structure of hydrogen bonds.
