GAS LAWS Motor ENERGY/GRAHAM’S LAW LAB Reason: To see how masses of particles and atoms influence their pace of dispersion, and clarify our perceptions as far as mass, speed, dynamic vitality and temperature. Warm-up Question: 1.     What is the meaning of temperature? Temperature is a proportion of the normal Kinetic Energy of the particles creating a material. 2.     What is the meaning of dispersion? Dispersion is an unconstrained spreading of particles until they are consistently circulated in their holder. 3.     If we increment the temperature of test of gas, at that point shouldn't something be said about the gas atoms should change? The gas particles would start to speed up since the temperature would increment. 4.     The component iodine (I2) diffuses more gradually than ethanol (CH3CH2CH2OH). Why would that be? Iodine is heavier in nuclear mass then ethanol, hindering its procedure to diffuse. Iodine weighs 253.6u while ethanol weighs 60.03u, giving ethanol a quicker disseminations rate. Methodology A: 1.     Obtain a glass cylinder and wash it with water. Dry the outside of the cylinder with a paper towel. Next, spurt some CH3)2CO into the cylinder.

Get forceps, mark them, "HC1" or â€Å"NH3"with tape, and spot them at their particular finish of the lab table. 6.     Record the temperature of the air around the cylinder in the information table. 7.     Separate the cotton ball into pieces sufficiently little to stuff into the parts of the bargains tube. Try not to place them into the cylinder yet. 8.     While holding the cotton ball with the forceps, place 4 drops of HCl or NH3 (whichever relates to the mark on the forceps). 9.     Repeat stage 8 with the other synthetic.
