4) In general, if the viscosity is very high at the melting position of the corresponding crystalline phase which would form the melt, it is much easier to form glass for this melt. True or False 5) The glass fiber is possible to have a tensile strength even larger than that for iron or structural steel. Therefore, in the practical applications, we should be able to use glasses for the same purposes of the iron or structural steel. True or False

I An adventurous archaeologist cros- ses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 5.43). The rope will break if the tension in it exceeds 2.50 × 104 N. Our hero's mass is 90.0 kg. (a) If the angle 0 is 10.0⁰, find the tension in the rope. Start with a free-body diagram of the archaeologist. (b) What is the smallest value the angle 0 can have if the rope is not to break? E

For each of the following statements, insert the letter T for True and Ffor false. Viscosity is a result of inter-molecular forces. The size and/or shape of the molecules will influence the viscosity. Long molecules that can become entangled will have a lower viscosity than a spherical molecule. The viscosity of a fluid increases with temperature.

The area of the plate-and-frame the press was 0.0439 m2, and the pulp concentration was 23.47 kg solid/m3 filtrate. a)      Convert the data in Table 1 into a graph. You can either use Excel or graph paper. Your graph should be self-explanatory. b)      Using the graph in (a), estimate the specific cake resistance and the resistance of the filter medium to filtrate flow.

esc DZL Homepage - Principles Chemistry II wLab Section 10 Spring 2024 CO O States of Matter Understanding consequences of important physical properties of liquids Liquid A is known to have a higher viscosity and higher vapor pressure than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment 40.0 mL of Liquid A are put in one sealed 5 L flask, and 40.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is then slowly lowered with a vacuum pump. A 250 mL beaker is submerged in a large container of Liquid A and turned upside down, and another 250 mL beaker is submerged and turned upside down in a large container of Liquid B. Hydrogen (H₂) s gas is bubbled into each upside-down beaker until 100 mL of liquid has been displaced. The masses m and me of hydrogen inside each beaker is then chemically determined. Note for advanced students: you may assume the solubility of H₂, in either liquid is very low.…
