atoms of the same element with different number of neutrons/mass

atoms of the same element with different number of electrons

both electrons and protons in an atom.

Which of the following properties of water enables molecules to cling together as they move from the roots to the leaves of plants?

Water exhibits cohesive behavior.

Capillary action is the result of adhesion. Which aspect of water is responsible for this?

Hydrogen bonds form between water and another substance.

Nonpolar covalent bonds enable water to dissolve other substances.

Polar covalent bonds join molecules of water to other substances.

Ionic bonds enable electrons to flow through water and into another substance.

Large bodies of water do not quickly fluctuate, or change, in temperature. Why?

Water has a high heat capacity.

Some insects can stand on the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?

The insects are light enough so they do not break the hydrogen bonds holding the water molecules together

The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.

The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.

The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next

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

Capillary action pulls the water molecules like a chain.

Water’s cohesion causes it to “pull” towards the leaves.

How does a hydrogen bond form?

Between the positive hydrogen of one water molecule and the negative oxygen of another

Between the positive hydrogen of one water molecule and the negative hydrogen of another

Between the positive oxygen of one water molecule and the negative oxygen of another

Between the positive hydrogen of one water molecule and the positive hydrogen of another

Many fish and aquatic plants can survive a cold winter because the layer of ice that forms at the top of the lake insulates the water below and prevents the lake from freezing solid. What unique property of water contributes to this effect?

Water expands and becomes less dense when it freezes.

Water absorbs heat when it evaporates and forms a gas

Water molecules completely separate into ions in solutions.

Water forms hydrogen bonds with ions and other polar substances.

In Florida, daytime and nighttime temperatures usually only differ by 5 to 10°C, while temperatures in the desert often differ by as much as 40°C. What role does water play in keeping temperatures in Florida from fluctuating dramatically?

Bodies of water store heat during the day and release it at night which keeps temperatures steady

Humid air releases heat as it rises, keeping temperatures constant

Evening rain brings heat from the upper atmosphere back to Earth

Water cools the land around it so that it never gets as hot as a desert.
