why absolute zero can never be achieved is included as well as a look at implications for the future. How close scientists have been able to come to achieving the
coldest temperature on Earth is discussed. Bibliography lists 5 sources. SA1420.rtf The concept of absolute zero is interesting and complex.
First, one must delve into other scientific facts, particularly as it concerns kinetic energy. Heat is the kinetic energy of molecules and when fuel is burned, for example, chemical energy
is released (Barnes-Svarney, 1995). The combustion sets molecules of gas into vigorous motion (1995). If an iron bar is heated, moving molecules in the flame bump into molecules in the
bar, it creates a situation where they are set in motion and that is what makes the bar hot (1995). One can experience this in many ways in daily life
such as when one touches the metal grates on the stove for example or touches a car that has been out in intense sunlight. Heat is the measure of
kinetic energy where all molecules are found in a system and perhaps the most common measure of heat is a calorie (Barnes-Svarney, 1995). People are familiar with counting calories that
their foods contain, but a calorie is technically a measure of heat. A calorie is the amount of energy required to raise the temperature of one gram of water
by one degree (1995). Temperature is the average kinetic energy of the molecules contained in any system (1995). In systems of measurement commonly used, most are based upon temperatures
at which water boils or freezes (1995). The fact that much is contingent on when something freezes or boils, poses an interesting problem. In reality, absolute zero has never been
