they spread out because they are moving and float above the cooler air
by wind heat energy is measured in joules
Substances that have internal movement(gas, liquid, and solids to a certain degree) will have convection currents. The concept is most easily understood in a gas. As gases are… heated their molecules travels faster and faster. The faster they move and the more the kinetic energy involved in the collisions causes the gas to increase in volume. This means that the particles are further apart and therefore the density of the gas decreases. And substances with lower density will rise. This can also be thought of as kinetic and potential energies. As the gas is heated the molecules inside have increased kinetic energy. The increased energy of the molecules allows the molecule to reach higher potential energy levels(which means the molecule can rise). jacquie s has a science test tomorow Hope that helps.
Think of these two factors in terms of a positive correlation. For example, the higher the temperature, the higher the density.
How it changes in response to its environment.

A promise to pay in a definite period (s) the money accepted known as principal and also to pay interest at the notified rate in periodical intervals.
Heat is the total energy of molecular motion in a substance; temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the spee…d of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy.
When a substance is heated, the molecules absorb heat energy and begins to vibrate to and fro thereby slightly expanding the substance.

Heat is conducted in solids by the speed of molecules or ionic crystals, or in the case of large molecules, the vibrations of parts of molecules. It can also be the excitement… or movement of electrons in molecules or crystals. For example when a metal, lets say copper, is heated, the loose electrons in the metallic crystal lattice move very fast within the crystal. When you touch the metal the collisions of the electrons in the metal surface causes the parts of the large molecules that make up the skin of your finger to vibrate facilitating heat exchange and "hot to the touch".
It's complicated and hard to explain, but I'll try my best. Evaporation occurs when a liquid changes to a gas, but only on the surface of the liquid volume. The gas molecules… transfer heat to the liquid molecules. An unequal distribution of heat causes some liquid molecules to become gas molecules. It is random and uneven. Energy from the sun also spawns evaporation. When evaporation does happen, the molecules that leave the liquid body takes a lot of heat with it, therefor the average temperature of the liquid decreases. Evaporation depends on heat, humidity, and air movement.
There are many different answers that could be attributed to this question. My first reccommendation would be to read anything and everything by Joseph Campbell. The main titl…e I would suggest is "Hero with a Thousand Faces" or "The Hero's Journey". A more specific answer for this question would be that the "Hero's Quest" suggests that a protagonist in a novel has risen from depression, lonliness, or some other outcast location, to defeat an outward or inward enemy in order to return to his original state of being.
