Properties of Water

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to the combination of cohesion (water molecules sticking to each other) and adhesion (water molecules sticking to other surfaces).

Front

What causes water droplets to take a spherical shape?

Back

Water droplets take a spherical shape due to cohesion, which is the attraction between water molecules that minimizes surface area.

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between particles of the same substance, such as water molecules attracting each other.

Front

What property of water allows it to flow against gravity?

Back

Capillary action allows water to flow against gravity by utilizing both cohesion and adhesion.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, meaning it has regions with partial positive and negative charges.

Front

Explain the concept of adhesion in water.

Back

Adhesion is the attraction between water molecules and different substances, allowing water to stick to surfaces.

Front

What role do hydrogen bonds play in water's properties?

Back

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

Front

How does water's polarity affect its solubility?

Back

Water's polarity allows it to dissolve many ionic and polar substances, making it an excellent solvent.

Front

What is surface tension and how is it related to water?

Back

Surface tension is the elastic tendency of a fluid surface that makes it acquire the least surface area possible, primarily due to cohesion among water molecules.

Front

Describe the significance of water's high specific heat.

Back

Water's high specific heat means it can absorb a lot of heat without a significant change in temperature, which helps regulate climate and maintain stable environments.
