Front

Why does water move from the roots to the leaves of plants?

Back

Back

Water molecules are attracted to other substances.

Front

Describe COHESION.

Back

Water molecules are attracted to other water molecules.

Front

What is the significance of water's polarity?

Back

Water's polarity allows it to dissolve many substances, making it a universal solvent.

Front

Explain the concept of surface tension in water.

Back

Surface tension is the cohesive force between water molecules at the surface, allowing it to resist external force.

Front

What role does water play in temperature regulation?

Back

Water has a high specific heat capacity, which helps regulate temperature by absorbing and releasing heat.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, which is why ice floats.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion.
