Properties of Water

Front

What is the reason water is called a universal solvent?

Back

Water is called a universal solvent because it can dissolve most substances due to its polar nature.

Front

Why does ice float on water?

Back

Ice floats on water because, as water freezes, it expands and its density decreases.

Front

What term describes the attraction of water to other substances?

Back

Adhesion is the term that describes the attraction of water to other substances.

Front

What property of water allows large bodies of water to maintain stable temperatures?

Back

Water has a high heat capacity, which allows large bodies of water to maintain stable temperatures.

Front

Which part of the water molecule has a slightly positive charge?

Back

The hydrogen end of the water molecule has a slightly positive charge.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows it to stick to itself, leading to surface tension.

Front

How does water's polarity contribute to its solvent properties?

Back

Water's polarity allows it to surround and separate ions and molecules, effectively dissolving them.

Front

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

Back

Surface tension is the cohesive force at the surface of water that allows it to resist external force.

Front

What is capillary action and why is it important for plants?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, important for water transport in plants.

Front

How does water's high specific heat affect climate?

Back

Water's high specific heat helps moderate climate by absorbing and releasing heat slowly.
