Which Of The Following Regarding Energy Is Correct? Energy can be created but not destroyed. Energy can neither be created nor destroyed. Energy cannot be created but can be destroyed. Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Which is
How Is Thermodynamics Used In Chemical Engineering? The main uses of thermodynamics in chemical engineering are to determine states of phase and chemical equilibrium necessary for the design of separations processes (i. e., distillation, absorption, extraction, etc.) and chemical reactors, and in determining the thermodynamic (2nd law) efficiency of chemical processes. Do Chemical Engineers study
Why Is The 2nd Law Of Thermodynamics True? The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative. Is the 2nd law of
Why Is The 2nd Law Of Thermodynamics Important? Why is the second law of thermodynamics so important? Second law of thermodynamics is very important because it talks about entropy and as we have discussed, ‘entropy dictates whether or not a process or a reaction is going to be spontaneous’. Why do we need the second
Why Is The 2nd Law Of Thermodynamics? The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered
Why Is Conservation Law Important? An important function of conservation laws is that they make it possible to predict the macroscopic behaviour of a system without having to consider the microscopic details of the course of a physical process or chemical reaction. Explanation of the principle of the conservation of energy. Why is law of
Are Heat And Temperature Inversely Proportional? (a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a mass m, you need to add twice the heat. … (c) The amount of heat transferred depends on the substance and its phase. Is there a proportional relationship between
Which Law Is Not A Basic Conservation Law? Law of conservation of mass. What are the 4 conservation laws in physics? Exact conservation laws include conservation of mass (now conservation of mass and energy after Einstein’s Theory of Relativity), conservation of linear momentum, conservation of angular momentum, and conservation of electric charge. Which of the
Why Is Carnot Cycle Impractical? Carnot cycles are not encountered in reality since achieving isothermal heat transfer is very difficult (needs very large heat exchangers and long time). Also process 3-4 requires a pump or compressor that can handle two phase mixture (liquid and vapor) which is impractical. Why is Carnot cycle not possible? In
What Direction Does Energy Always Flow? And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time. Does heat
