Ethylene enters a reversible, isothermal, steady-flow compressor at 1 bar and 280 k, and exits at 40 bar. find the required compressor work (kj/kmol) using the ideal gas equation of state.

Required compressor work W=8560.44  KJ/Kmol

Explanation:

Given that

Initial pressure = 1 bar

Final pressure = 40 bar

Process is isothermal and T=280 K

We know that ,work done in isothermal process given as

given taht gas is ideal so

P V =m R T

R for ethylene

R=0.296 KJ/kg.K

Now by putting the values

W= -305.73 KJ/kg

Negative sign indicates that work done on the system.

Required compressor work W=305.73 KJ/kg

Molar mass of ethylene M= 28 Kg/Kmol

So W= 305.73 x 28  KJ/Kmol

W=8560.44  KJ/Kmol

Required compressor work W=8560.44  KJ/Kmol

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
