The answer is 7.06g If liquid water is open to the environment, evaporation can happen at...
A cold beverage can be kept cold even a warm day if it is slipped into a porous ceramic container that has been soaked in water. Assume that energy lost to evaporation matches the net energy gained via the radiation exchange through the top and the side surfaces. The container and beverage have temperature T = 16°C, the environment has temperature Tenv = 32°C, and the container is a cylinder with radius r = 2.42 cm and height 11 cm....

Hi! Can you please answer questions a and b for my organic lab report :) The pictures below the questions is my lab procedure. Thank you 6. Analysis Questions: a) This lab utilized a new technique called reflux, and the use of a condenser tube while heating the reaction. What is the purpose of the condenser? Why not just heat the reaction in a closed vessel instead? b) A student misread the instructions and first refluxed the sodium methoxide in...
Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...

Two large parallel plates with surface conditions approximating those of a blackbody are maintained at 800°C and 100°C, respectively. Determine the rate of heal transfer by radiation between the plates in Wim and the radiative heat transfer coefficient in W/m K ) 12 Write down the one-dimensional sent heal conduction equation for a plane wall with constant thermal conductivity and heat generation in its simplest form, and indicate what each variable represents 13 Write down the one-dimensional transient heat conduction...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
