What is the chemical formula for water?

Back

H₂O

Front

What property of water allows it to be such a versatile solvent that it is often called the 'universal solvent'?

Back

Polarity.

Front

What is cohesion?

Back

Water's ability to stick to itself.

Front

What is capillary action?

Back

The ability of water to flow in narrow spaces without the assistance of external forces, resulting from both adhesion and cohesion.

Front

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

Back

It allows water to absorb and store large amounts of heat, helping to regulate temperature in the environment.

Front

What does it mean for water to expand upon freezing?

Back

Water molecules arrange themselves in a way that makes ice less dense than liquid water, causing ice to float.

Front

What is surface tension?

Back

The cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane.

Front

How does water's polarity affect its interactions with other molecules?

Back

Water's polarity allows it to form hydrogen bonds with other polar molecules, making it an excellent solvent.

Front

What is the role of water in biological systems?

Back

Water is essential for life, serving as a solvent, a medium for chemical reactions, and a means of temperature regulation.
