The temperature - Essay Example

The Temperature “Temperature is the heat of an object, measured by its intensity or degree on a defined scale” (Elizabeth, . A gas constitutes molecules that travel in different directions with different velocities. Some molecules move faster as compared to the others (Cool Cosmos, n.d.). Temperature of a substance measures the average thermal energy or heat of its atoms and and/or molecules. Planck temperature is considered to be the maximum attainable temperature (Anissimov, 2011). There are numerous forms of energy including heat energy, gravitational energy, light energy, electrical energy, mechanical energy, nuclear energy, chemical energy and sound energy.

Energy can transform from one form to another and it can also be transferred between different mediums. When a man floats in cold water whose temperature is significantly lower than his own body temperature, the energy flows from his body into the water. Consequentially, the man starts to become colder while the water around his body starts to rise in temperature. When this happens, its not heat that is transferred, rather it is the man’s internal energy. “.heat and internal energy are two quite different things; the energy associated with microscopic motions and forces is internal energy, not heat” (Reynolds and Perkins cited in Watson, 2010).

The term renewable fuel is used for natural resources which reform faster than they are consumed. Various physical and biogeochemical processes are involved in the replenishment of natural resources (Think Quest, n.d.). According to this definition of renewable fuels, almost all types of resources are renewable resources. Humans need to adopt ways that would allow those resources to replenish faster than the rate at which they consume them. Nevertheless, this is not always possible, particularly with resources such as oil and coal which take too long to replenish.

Alternate renewable resources include water, solar power, air and trees.
