Nitrogen gas at 300 k and 200 kpa is throttled adiabatically to a pressure of 100 kpa if the change in kinetic energy is negligble the temperature of the nitrogen after throttling will be:

The temperature of the Nitrogen after throttling is  

Explanation:

From the question we are told that

   The  temperature is  

    The pressure is  

    The pressure after being  

Generally from the first law of thermodynamics we have that

Here  is the change internal  energy which is mathematically represented as

Here       is the specific heat of the gas at constant pressure

         is the change kinetic energy which is negligible

         Q  is the thermal  energy  which is Zero for an adiabatic process

         W  is the work done and the value is zero given that the gas was throttled adiabatically

So

=>  

=>  

=>  

the answer is 75.0%.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
