GAS LAWS Active ENERGY/GRAHAM’S LAW LAB Reason: To see how masses of iotas and atoms influence their pace of dispersion, and clarify our perceptions regarding mass, speed, motor 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 making a material. 2.     What is the meaning of dissemination? Dissemination is an unconstrained spreading of particles until they are consistently circulated in their compartment. 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 atoms 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. Strategy 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 compares to the name on the forceps). 9.     Repeat stage 8 with the other concoction.

The author of the reading feels there is evidence to suggest that dinosaurs were animals of this type. The professor, on the other hand, is not convinced of this. He casts doubt on each of the theories presented in the reading. First of all, the author points out that dinosaur fossils have been found in cold polar regions. It is noted that only animals that can maintain warm body temperatures, like endotherms, coul d have been active in climates of this type. The lecturer casts doubt on this claim. She observes that today’s polar regions were much warmer during the time of the dinosaurs; warm enough for non-endotherms to inhabit them. Moreover, she observes that such animals could have migrated or hibernated during months when the temperatures actually were very cold. Secondly, the author contends that the dinosaurs were endotherms based on the structure of their legs. The article points out that dinosaurs had legs underneath their bodies, just like all modern endotherms. On the other hand, the lecturer notes that the leg structure of dinosaurs served merely to support their weight. She contends that having legs under their bodies allowed the dinosaurs to evolve to very large sizes, which was advantageous in many ways. Finally, the author makes a connection between endothermic animals and bone structure. The bones of dinosaurs contained bodies called Haversian canals, which helped th em to grow large, which is a common characteristic of endotherms. The professor challenges the validity of this point. She notes that dinosaur bones also show evidence of growth rings. She says that these rings indicate that the dinosaurs grew in spurts, which is a characteristic of non-endotherms.NoteThis is a sample TOEFL integrated essay written by a native speaker.
