Water Properties

Front

What is a nonpolar compound?

Back

A nonpolar compound is a molecule that does not have distinct positive and negative ends, meaning it does not dissolve well in water.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of chemical bond where electrons are shared unequally between atoms, resulting in a molecule with a slight charge difference.

Front

What is cohesion in the context of water?

Back

Cohesion refers to the attraction between water molecules, which causes them to stick together, as seen when water forms droplets.

Front

What is the significance of water's density when it freezes?

Back

Water expands when it freezes, making ice less dense than liquid water, which allows ice to float.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, such as in the roots and stems of plants.

Front

What is the universal solvent?

Back

Water is often called the universal solvent because it can dissolve more substances than any other liquid.

Front

What is surface tension?

Back

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

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a substance by one degree Celsius, and water has a high specific heat.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds are weak attractions between water molecules that contribute to water's unique properties, such as cohesion and high specific heat.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons between atoms, while covalent bonds involve the sharing of electrons.
