Provide a definition for the property 'Polar'.
A molecule with regions of partial positive and negative charges due to unequal sharing of electrons.
A molecule with only nonpolar covalent bonds and no charge separation.
A molecule that contains only ionic bonds.
A molecule that does not interact with water due to equal sharing of electrons.
Provide an example of the function of 'Polar' property in the environment or biological systems.
Water's polarity allows it to dissolve many substances, making it a good solvent in biological systems.
Water's polarity prevents it from mixing with any other substances.
Polar molecules are always non-reactive in biological systems.
Polarity causes water to freeze at room temperature.
Provide a definition for the property 'Cohesive'.
The attraction between molecules of the same substance, such as water molecules sticking together.
The ability of a substance to dissolve in water.
The process by which plants lose water through their leaves.
The tendency of molecules to move from an area of high concentration to low concentration.
Provide an example of the function of 'Cohesive' property in the environment or biological systems.
Cohesion allows water to move up plant stems in a process called capillary action.
Cohesion causes water to evaporate quickly from leaves.
Cohesion prevents water from mixing with other liquids.
Cohesion makes water molecules repel each other.
Provide a definition for the property 'Adhesive'.
The attraction between water molecules and different substances.
The ability of water to resist changes in temperature.
The process by which water evaporates from leaves.
The force that holds water molecules together.
Provide an example of the function of 'Adhesive' property in the environment or biological systems.
Adhesion helps water stick to the walls of plant vessels, aiding in water transport.
Adhesion causes water to evaporate faster from leaves.
Adhesion prevents water from mixing with other substances.
Adhesion allows water to freeze at higher temperatures.
Provide a definition for the property 'High surface tension'.
The tendency of water molecules to stick together at the surface, creating a 'skin' due to hydrogen bonding.
The ability of water to dissolve many substances due to its polarity.
The process by which water evaporates at low temperatures.
The property of water to conduct electricity efficiently.
Provide an example of the function of 'High surface tension' in the environment or biological systems.
High surface tension allows insects like water striders to walk on water surfaces.
High surface tension causes water to evaporate quickly from lakes.
High surface tension prevents ice from forming on water surfaces.
High surface tension allows fish to breathe underwater.
Provide a definition for the property 'Less dense as a solid than as a liquid'.
Water expands and becomes less dense when it freezes, so ice floats on liquid water.
Water contracts and becomes more dense when it freezes, so ice sinks in liquid water.
Water remains the same density when it freezes, so ice neither floats nor sinks.
Water evaporates and becomes less dense when it freezes, so ice turns into vapor.
Provide an example of the function of 'Less dense as a solid than as a liquid' in the environment or biological systems.
Ice floating on water insulates aquatic life in lakes and ponds during winter.
Salt dissolving in water increases its density.
Water vapor rising above liquid water forms clouds.
Liquid water freezing at the bottom of lakes.
Provide a definition for the property 'High specific heat'.
Water requires a lot of energy to change temperature due to hydrogen bonding.
Water freezes at a lower temperature than most liquids.
Water evaporates quickly when heated.
Water has a low boiling point compared to other liquids.
Provide an example of the function of 'High specific heat' in the environment or biological systems.
High specific heat helps regulate Earth's climate and maintain stable temperatures in organisms.
High specific heat causes rapid temperature changes in water bodies.
High specific heat leads to increased evaporation rates in deserts.
High specific heat prevents water from freezing at any temperature.
