Black Jack man gets 20 years for robberies in St. Charles County

ST. CHARLES COUNTY • Christopher Gillispie, 26, of the first block of Edgemere Court in Black Jack, was sentenced today to 20 years in prison for three robberies in St. Charles County.

Gillispie pleaded guilty on four counts of robbery, three counts of armed criminal action, one count of felonious restraint and one count of tampering with a motor vehicle, all felonies.

During one of the robberies, at a gas station in St. Charles, Gillispie took money from a customer he held at gunpoint and the cash register, prosecutors said.

Circuit Judge Nancy Schneider confirmed the terms of a plea agreement in sentencing him to concurrent sentences of Gillispie 20 years in prison for each robbery and armed criminal action and has seven years for the reservoir and trap charges falsification, prosecutors said.

State law requires that Gillispie serve at least 85 percent - 17 years - of his sentence on the robbery charges before he was eligible for release.

Deputy Prosecutor Steven Kobal represented the state. Assistant Public Defender Sara Serot represented Gillispie.

Robert Boyle studied the effect of pressure changes on the volume of the gases. For this purpose, he designed a J – shaped glass tube and its shorter arm was closed. He then poured mercury in the longer arm so as to enclose some amount of air in the shorter arm. The equal level of mercury in the two arms indicated that the confined air was subjected to the atmospheric pressure. If the volume of a gas is plotted against the total pressure, parabolic curve is obtained showing the decrease in volume with increasing pressure.A graph of volume with I / P gives a straight line from Boyle's law is interpreted in terms of molecules. Applying pressure causes the molecules closer causing volume reduction. Mathematically, Boyle's law can be represented as follows:

V? 1 / P (constant temperature) is a matter of common observation that substances expand on heating and contract on cooling. Volume change due to expansion and contraction is very low in the case of solids and liquids because of their compact structure and lack of inter molecular spaces.Gases have enormous changes due to the presence of large inter molecular spaces.Changes of volumes of gases due to changes of temperature at constant pressure were studied by charles’s.(1746-1823). V1 / T1 = V2 / T2 = K

This is the mathematical representation of Charles’s law which is used while solving the problems on Charles’s law. When the volume of a gas is plotted against the temperature, a straight line is obtained. If this straight line is extra plotted, it will be seen that it intercepts the temperature axis at – 273.16 degree C. It suggests that the volume of a gas would theoretically be zero at -273.16 degree C.In fact this temperature has never been achieved for any gas.In fact all the gases condense to liquid at a temperature above this point,so that gas behaviour can no longer be observed.The temperature of -273.16 degree C is referred to as the absolute zero to zero degree of the absolute scale (Kelvin Scale). At absolute zero,the volume of gases in considered to be zero and all the motion ceases to exist.As already pointed out that centigrade scale is changed into Kelvin scale by adding 273.

Graham’s Law Of Diffusion: Diffusion means mixing up of molecules of different gases moving in opposite directions. We know that gas molecules are constantly moving in haphazard direction.
