in the manufacture of pulp from the delignification process using an operating temperature of 100C. The types of solvents used include acetic acid and ethanol. the other variables are considered the same. why during the delignification process using a temperature of 100 C?

Shape memory polymers are a class of materials that can remember their original shape and transition between shapes when stretched, twisted, or compressed. They have recently found uses in orthopedics and as other surgical and dental implants. One of the most promising new materials is PEEK (polyether ether ketone). It is a very good electrical and thermal insulator. As a dental implant material, it provides the patient a comfortable implant that does not conduct heat or alter taste, which can be a constant bother with traditional materials (see the photo). Imagine a PEEK implant that is 1.612 cm in length with a circular radius of 1.327 mm. Note that 1 meter = 100 cm = 1000 mm. An ice cube is in contact with the end of the implant. How much heat is transferred along the length of the implant in 36 seconds, if the change in temperature across the implant is 27 °C? The thermal conductivity of PEEK is 0.25 W/(m · C°). Note that your answer is a small number, indicating that this implant…

You have been provided with a graph labelled Graph A (See Microsoft Teams or click here) that is the phase diagram for a Copper-Gold system. Use this figure to answer the questions below and show your work. a. If you have a 200g sample that is 10 wt% copper at 932°C, what is the minimum amount of copper you would need to add at this temperature to form a completely liquid phase for this sample? b. If you have a 200g sample that is 10 wt% copper at 932°C, what is the minimum amount of gold you would need to add at this temperature to form a completely solid phase for this sample?

In an attempt to conserve water and to be awarded LEED (Leadership in Energy and Environmental Design) certification, a 20.0x 103 L cistern has been installed during construction of a new building. The cistern collects water from an HVAC (heating, ventilation and air-conditioning) system that is designed to provide 100 x 105 ft/min air at 22.0°C and 40.0 % relative humidity after converting it from ambient conditions (35.0 °C, 86.0 % relative humidity). The collected condensate serves as the source of water for lawn maintenance. Assume P-1 atm. Physical Property Tables Input Air Correct. Estimate the intake of air at ambient conditions in cubic feet per minute. 1.068 x 10 ft/min
