Answer:
The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.
The answer is D. Phospholipids are diglycerides (two fatty acid chains covalently bonded to a glycerol molecule)
that are covalently bonded to a phosphate group by an ester linkage. Fatty
acids are long chains that are mostly made up of hydrogen and carbon, while
phosphate groups consist of a phosphorus molecule with four oxygen molecules
attached. Glycerol is a 3 carbon chain containing hydroxyl groups in each of the carbon.
Hot air always rises from the equator. As this air climbs higher in the sky, it cools. Cool air can hold less water than warm air. This means that as the air cools, clouds form that release most of the water they hold. Because the cooling air is above the equator, the moisture rains back down on the tropics.
