Heat and Temperature
Heat and Temperature

Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same, but they are not.” Heat and Temperature, para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place when heat is being examined. To examine the heat capacity of a substance various properties exist, along with different forms of heat. When thought about, everyone has been exposed to heat in some type of way but never even question what has to happen in order to encounter that sensation. The textbook states that “the term heat is used to describe the “something” that moves between objects when two objects of different temperatures are brought together.’ ( Tillery , Bill W., Enger, Eldon D., Ross, Fredrick C. p.82) Temperature on the other hand, can be defined as the degree of hotness or coldness of an object. The two are related due to the fact that heat is energy and temperature is basically a number used to determine the energy given by the molecules within a substance, which directly relates to the kinetic energy. The kinetic theory of matter and heat coincide with each other because the theory states that all materials are made up of either particles, molecules or atoms that are constantly moving. As to which when heat is displayed it is said that thermal energy is being transferred from a higher temperature to a lower one, meaning that particles have basically started to speed up. The idea of heat and temperature may seem very complex, but only because it happens so fast that most individuals do not even have a clue as to what is causing the reaction that they get when they raise the temperature in order to get heat. There are many differences between

    In every reaction, energy is transferred between a system and its environment. A system encompasses the substances that are involved in a reaction, and everything else in the universe other than the system is called the environment. The standard SI unit of energy is Joules (J). Temperature is the level of excitement of the atoms in a substance. In most cases, energy is transferred by heat. Heat is the energy released from a change in temperature. The standard units for heat and temperature are in degrees Celsius or Kelvin (both have the same increment between each degree, the difference is that Celsius is based off…

    * Remember that temperature is a measure of the average kinetic energy of the particles in a substance. This means that the addition of heat to a solid causes the vibration of the particles to increase more and more as the temperature of the solid increases. This increase in vibration will continue until, at a certain temperature, the vibrations are rapid enough to break up the fixed arrangement of particles. At this point a solid will begin to melt into a liquid.…

    When you look perfectly at white clothes, all the colors are being absorbed by the electron in the atoms of the elements in the dye, causing the electrons to become “excited”, and emit all frequencies of light back to your eyes. All the energy of the photons red, orange, yellow, blue, indigo, and violet light is sent right back to the air around the white shirt. So none of the energy is absorbed by atoms and converted into kinetic energy of atoms. Temperature measures the kinetic energy of the atoms. So if there is no increase of kinetic energy this means that there will be no increase of temperature in the lighter colored clothes.…

    The body gains and loses heat through the external environment by radiation, conduction, convection and evaporation of water. These are all physical mechanisms known to the human body. (Vander, Sherman & Luciano 1998). Radiation is an infrared energy between two objects that have no physical contact with each other. Heat is gained by radiation from the sun, hot sand on the beach and hot coal. Heat can also be lost as radiation to cool vegetation, water in the sea and snow on the ground. (Seeley, Stephens & Tate 2002). Conduction is the exchange of heat between two objects, which have direct contact with each other (Seeley, Stephen & Tate 2002). Using conduction heat moves from areas of high to low temperature. This usually occurs in the body when a person comes in to contact with a cold surface/object. For example if a person sits on a cold surface with no or poorly insulated clothing then this could cause heat loss. This is particularly dangerous in the elderly when they fall to the ground and become unconscious especially in cold conditions. (Watson 1998). Convection is the transfer of conductive heat between the body and the air; it moves warm air away from the body to be replaced by cooler air. (Seeley, Stephens & Tate 2002). Convection occurs as a result of air currents, which is why we get colder much quicker in windy conditions and why fans cool us down. (Watson 1998). Evaporation is the conversion of water from a liquid to a gaseous form. Heat is lost when water evaporates from the body surface. (Seeley, Stephen & Tate 2002).…
