Front

What kind of molecule is water?

Back

Water is a polar covalent molecule, meaning it has a partial positive charge on one side and a partial negative charge on the other.

Front

What is the molecular structure of water, H2O?

Back

The molecular structure of water consists of one oxygen atom covalently bonded to two hydrogen atoms, forming a bent shape.

Front

Why is water considered a universal solvent?

Back

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

Front

What is the independent variable in an experiment testing the effect of salinity on anchovy populations?

Back

The independent variable is the level of salinity in a given area.

Front

At what temperature does water boil?

Back

Water boils at 100°C (212°F) at standard atmospheric pressure.

Front

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

Back

Water's high specific heat allows it to absorb and release large amounts of heat without significant temperature changes, stabilizing climates.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows molecules to stick to each other, leading to surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances, which is important for processes like capillary action.

Front

What is the pH level of pure water?

Back

The pH level of pure water is 7, which is considered neutral.

Front

What happens to water when it freezes?

Back

When water freezes, it expands and becomes less dense, allowing ice to float on liquid water.
