DETERMINATION OF SOFTENING POINT STANDARD IS: 1205 – 1978. DEFINITION Softening point is the temperature at which the substance attains a particular degree of softening under specified conditions of test. APPARATUS • Standard Ring and Ball Apparatus. • Steel balls 2 No, each 9.5mm in diameter and weighing 3.5 + 0.05 grams. • Brass rings 2 No, the rings shall be tampered and shall confirm to the following Depth: 6.4 + 0.1mm Inside diameter at bottom: 15.9 + 0.1mm Inside diameter at top: 17

"Teen Mom OG" star Farrah Abraham is not going to take being fired lightly. According to The Blast, Farrah is suing Viacom for $5 million over the loss of her job in the "Teen Mom" franchise. In the documents, it says she was "wrongfully terminated her employment because she did not conform to gender stereotypes." Details about Farrah's lawsuit According to Farrah back in October of 2017, executive producer Morgan J. Freeman came to her home in Texas to confront her. Morgan is the producer for "16

How does a physical or chemical change affect the mass of a substance within a closed system? Our hypothesis to this question was, if a chemical change affects the mass, then the mass will change. Our second hypothesis was, if a physical change occurs, then the mass would stay the same. Changes in matter happen all around us everyday. When we use a coloured pencil, they change in the size of how hard you are pushing on the coloured pencil which dulls it out. When you chew food it, changes its size

The academic principle I chose is a second-grade science standard. This standard is S2P1. Students will investigate the properties of matter and changes that occur in objects. a. Identify the three common states of matter as solid, liquid, or gas. b. Investigate changes in objects by tearing, dissolving, melting, squeezing, etc. During this movement pattern, we will be focusing on identifying the three states of matter as solid, liquid, and gas. For the movement pattern, I will instruct the students

Conservation of mass means in a chemical or physical change, mass can not be created or destroyed,so the mass will always stay the same but only with a closed system. This all relates to the experiments we have done in class. In experiment 2.1 we found out if the mass changed when salt dissolves in water. We found that it did not. This experiment was a physical change because you didn’t create something new.The reactants we had in this experiment were the the water and salt. The products were

For the second part of the experiment, choose your heaviest weight from the three that you use earlier. Then, move the laser 1 cm away from the string to obtain better results. Next turn on the wave driver and find the resonant frequency for the fundamental node of this string by playing with the frequency until the amplitude is maximized. Record this frequency. Now set up to plot Lissajous figures with the photodiode signal and the drive signal. This parametric plot will allow you to find the other

Figure 4.21 shows the magnetic hysteresis loop of CoFe2-xZnxO4 powders at room temperature, with a maximum applied field of up to 8 kOe. The saturated magnetization, remanence and coercivity are summarized in Table 4.10. Also, Figure 4.22 presented variations of saturated magnetization and coercivities for CoFe2-xZnxO4 powders as a function of compositions calcined at 900 ºC for 48 h. The magnetization value of doped samples increased sharply with the external magnetic field strength at the low field

Use the data given and developed graph to answer the questions on the attached worksheet. Investigation Questions: Describe the general trends that you see in the temperature over time: As time increased the temperature of the gases also increased. As the gases gain more energy the temperature also increased. Did one gas warm more quickly than the other? YES H2O increased the fastest. Was the increase in temperature gradual or were there changes in the slope of the line? The rise in temperature
