As the process is isothermal, so no change in internal energy takes place, that is, Q=W. Q=−630RJ 2. Work done in the isochoric process (2⇒3) is zero as no change in volume takes place and the amount of heat transfer is the same as the change in internal energy which is ...
As a result, the internal energy of the gas will tend to fall, as it supplies the energy necessary to do the work.But the internal energy of a gas depends on its temperature. So the temperature of the gas will also tend to fall. As metal is a good conductor of heat and the ...
1) isothermal process 等温过程1. In this paper,the internal energy and heat of the polytropic process,the adiabatic process and the isothermal processes of the varying mass system are discussed. 讨论了变质量系统的多方过程、绝热过程及等温过程的能量关系,并与常质量系统的多方过程、绝热过程及等温过程...
- Adiabatic Process: An adiabatic process is one in which no heat is exchanged between the system and its surroundings. In this process, any change in the internal energy of the system is due solely to work done on or by the system. 2. Heat Transfer: - Isothermal Process: There is heat...
1. Describe an imaginary process that satisfies the first law but violates the second law of thermodynamics. 2. Consider the process of baking potatoes in a conventional oven. Can the hot air in the o Provide two examples in which the mechanical energy of a system remains constant. ...
According to the energy storage system disclosed by the utility model, the underwater pressure is used for leading the inside of the air storage device to be in constant pressure, and a process of approximately-isothermal compressing and expanding is realized by the using of the measures of ...
3.The first process in the cycle isisothermal. 循环中的第一个操作缓冲操作 到温度。 「Crash Course Physics 速成物」评价该例句:好评差评指正 Crash Course Physics 速成物 4.The third process is the opposite of the first one, and it's alsoisothermal. ...
aHowever, such theoretical process is not easy to realize in practice. As for an isothermalexpansion, a heat source is needed for energy input into the system because the internal energy of gas remains constant during isothermal expansion. Obviously, there exists no such heat source in the ...
The Fluid Catalytic Cracking (FCC) is an important process in a refinery used mainly to produce higher value gasoline from heavy hydrocarbons. An FCC unit ... S Benyahia,A Gonzalez Ortiz,JI Paz Paredes - 《International Journal of Chemical Reactor Engineering》 被引量: 42发表: 2003年 ...
During this process, the intake and exhaust valves are closed, and the air in cylinder is no mass exchange process, only the energy exchange process. The more sufficient the expansion process, the higher the energy utilization efficiency of compressed air and the low of air temperature in the ...
