- Please show the complete solution. (Example: Conversion of Units) How much heat in kJ must be transferred to 20 kg of air to increase the temperature from 20 Degree Celsius to 280 Degree Celsius if the pressure is maintained constant?1. Immiscible components do not mix in the liquid phase, and each independently exerts its saturation pressure until they rach a certain phase they can form homogenous mixture? 2. It will be easier to separate the components of a vapor micture if they have the same concentration. True or False1. Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2. Based on data on the rate of energy consumption per year from question no. 1, if the growth rate energy 2.5% per year, calculate the doubling time (td) and what is the approximate rate of energy growth in 2021.

- 1. Visualize a substance with the following points on the phase diagram: a triplepoint at 0.05 atm and 150 K; a normal melting point at 175 K; a normal boiling pointat 350 K; and a critical point at 2.0 atm and 450 K. The solid liquid line is “normal”(meaning positive sloping). For this, complete the following:a. Roughly sketch the phase diagram, using units of atmosphere and Kelvin. Labelthe area 1, 2, and 3, and points T and C on the diagram.b. Describe what one would see at pressures and temperatures above 2.0 atmand 450 K.c. Describe the phase changes from 50 K to 250 K at 1.5 atm.d. What exists in a system that is at 1 atm and 350 K?e. What exists in a system that is at 1 atm and 175 K?2. Based from the phase diagrams of water and carbon dioxide, answer thefollowing questions and justify your answers: 1. You have ice at 263 K (-10.0 oC)and 1.0 atm. What could you do to make the ice sublime? 2. A sample of dry ice(solid CO2) is cooled to 173 K (-100.0 oC), and is set on a table at…In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)2.00 moles of nitrogen gas at 25.0 °C, confined within a cylinder by a piston maintaining a constant pressure of 1.00 atm, is heated with 3.90 kJ of energy. Assume all the energy is used to do work of expansion of the gas at 1.00 atm. What will be the final temperature (in °C) of the gas? Recall ∆H = ∆E + P∆V and watch your units!

What is the composition of the melt at T=1650C? b. What is the composition of the melt at T=1300C (if the temperature is at 1300C)? c. What conditions are needed in order for Anorthite (An), Diopside (Di) and liquid to exist in the system?Exhaust gas from an automobile contains air and 10-4 mole fractions of NO in air at 25 degC and 1.2 atm. Express this concentration as a mass concentration (kg/m3). Remember that the MW of NO is 30 g/molThe composition of a liquid with suspended solid particles is generally characterized by the fraction of solid particles either by weight or mass, Cs, mass = ms/mm or by volume, Cs, vol = Vs /Vm where m is mass and V is volume. The subscripts s and m indicate solid and mixture, respectively. Develop an expression for the specific gravity of a waterbased suspension in terms of Cs, mass and Cs, vol.
