What is the chemical formula for water?
Click to flip
The chemical formula for water is H₂O.
Click to flip
What type of chemical compound is water?
Click to flip
Water is an oxide, specifically a compound of hydrogen and oxygen.
Click to flip
Why is water considered a polar molecule?
Click to flip
Water is considered polar because it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Click to flip
What is the role of hydrogen bonds in water?
Click to flip
Hydrogen bonds cause water molecules to stick together, leading to water's unique properties like high surface tension.
Click to flip
How does the polarity of water affect its solvent capabilities?
Click to flip
The polarity of water allows it to dissolve many substances, making it a universal solvent.
Click to flip
At what temperature does water freeze and boil at standard atmospheric pressure?
Click to flip
Water freezes at 0°C and boils at 100°C under standard atmospheric pressure.
Click to flip
What is the density of water at 4°C?
Click to flip
The density of water at 4°C is approximately 1 g/cm³.
Click to flip
What property of water causes ice to float?
Click to flip
Ice is less dense than liquid water due to the lattice structure formed by hydrogen bonds, causing ice to float.
Click to flip
What is the significance of water's high specific heat capacity?
Click to flip
Water's high specific heat capacity allows it to absorb and release large amounts of heat without a significant change in temperature.
Click to flip
How does water's surface tension benefit living organisms?
Click to flip
Water's high surface tension allows certain insects to walk on water and supports water transport in plants.
Click to flip
What are the three common states of water on Earth?
Click to flip
The three common states of water on Earth are solid (ice), liquid (water), and gas (water vapor).
Click to flip
Why is water essential for life?
Click to flip
Water is essential for life because it is a solvent for biochemical reactions, helps regulate temperature, and is involved in nutrient transport.
Click to flip
How is water involved in the hydrological cycle?
Click to flip
Water is involved in the hydrological cycle through processes like evaporation, condensation, precipitation, and infiltration.
Click to flip
What happens to water molecules during the process of condensation?
Click to flip
During condensation, water molecules lose energy and transition from a gas (vapor) to a liquid state.
Click to flip
What is the role of water in photosynthesis?
Click to flip
In photosynthesis, water provides electrons and protons and releases oxygen as a byproduct.
