Question
Which of the following is true for the adiabatic expansion of a gas?
Selected Answer:
2.
pressure decreases
pressure is constant
1. The name of an engine cycle, describing most internal combustion engines using adiabatic compression to initiate ignition of a fuel air mixture 2. A real engine cycle, having a higher efficiency than an internal combusion engine 3. A theoretical engine cycle, having the maximum thermodynamic efficiency possible operating between a hot reservoir and a cold reservoir 4. The name of an engine cycle, describing most internal gassoline combustion engines using a spark plug to initiate ignition of a fuel air mixture 5. A real engine cylce that describes the use of steam to produce work at most power plantsWhich of the following is true for the adiabatic expansion of a gas?
Selected Answer:
2.
pressure decreases
pressure is constant
Explanation / Answer
Part 1 ans : statement 2:A real engine cycle, having a higher efficiency than an internal combusion engine
Part 2 ans: pressure decreases, no heat exchange.
