$100 Question Water is polar. What does this mean? Because water is very polar, it is the universal _____

$100 Answer Water molecules have 2 hydrogen atoms and 1 oxygen atom. Polarity means a clear positive end and negative end. Solvent

$200 Question Water is cohesive. What does this mean? Give an example of how this helps organisms.

$200 Answer Water molecules are attracted to each other. This causes surface tension and water droplets on waxy leaves

$300 Question Water is adhesive. What does this mean? Give an example of how this helps organisms.

$300 Answer Water molecules can be attracted to certain surfaces. This allows capillary action

$400 Question Water is _____ dense as a solid. What does this mean? Give an example of how this helps organisms.

$400 Answer Ice floats instead of sinking. This prevents flooding, and allows for lakes to remain only partially frozen in winter.

$500 Question What property of water does each example belong to? -meniscus -ice floating -water traveling from the roots of a plant up to the leaves -water droplets on a waxy leaf

$500 Answer -meniscus: ADHESION -ice floating: H2o LESS DENSE AS SOLID -water traveling from the roots of a plant up to the leaves: ADHESION -a bug sitting on the surface of H2O: COHESION
