Click on the flashcard to see the answer



What is the chemical formula for water?

The chemical formula for water is H₂O.

What type of chemical compound is water?

Water is an oxide, specifically a compound of hydrogen and oxygen.

Why is water considered a polar molecule?

Water is considered polar because it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.

What is the role of hydrogen bonds in water?

Hydrogen bonds cause water molecules to stick together, leading to water's unique properties like high surface tension.

How does the polarity of water affect its solvent capabilities?

The polarity of water allows it to dissolve many substances, making it a universal solvent.

At what temperature does water freeze and boil at standard atmospheric pressure?

Water freezes at 0°C and boils at 100°C under standard atmospheric pressure.

What is the density of water at 4°C?

The density of water at 4°C is approximately 1 g/cm³.

What property of water causes ice to float?

Ice is less dense than liquid water due to the lattice structure formed by hydrogen bonds, causing ice to float.

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

Water's high specific heat capacity allows it to absorb and release large amounts of heat without a significant change in temperature.

How does water's surface tension benefit living organisms?

Water's high surface tension allows certain insects to walk on water and supports water transport in plants.

What are the three common states of water on Earth?

The three common states of water on Earth are solid (ice), liquid (water), and gas (water vapor).

Why is water essential for life?

Water is essential for life because it is a solvent for biochemical reactions, helps regulate temperature, and is involved in nutrient transport.

How is water involved in the hydrological cycle?

Water is involved in the hydrological cycle through processes like evaporation, condensation, precipitation, and infiltration.

What happens to water molecules during the process of condensation?

During condensation, water molecules lose energy and transition from a gas (vapor) to a liquid state.

What is the role of water in photosynthesis?

In photosynthesis, water provides electrons and protons and releases oxygen as a byproduct.
