Answer:
(A) Adding Nitrogen
Explanation:
R11 or R123 are flammable substance under certain conditions when mixed with Oxygen, adding Nitrogen is a safety procedure used in displacing any R11 or R123 which are considered as hazardous when mixed with Oxygen.
Answer:
Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted.

Answer:
linear partial differential
Explanation:
The Schrödinger equation is a linear partial differential equation that describes the wave function or state function of a quantum-mechanical system. It is a key result in quantum mechanics, and its discovery was a significant landmark in the development of the subject.
Answer:I am so sorry but here are no questions, thanks for the points
Explanation:Have a nice day
Answer:
(a) The power input to the compressor: 
(b) The volume flow rate of the refrigerant at the compressor inlet: 
Explanation:
(a)
We need to check the values of enthalpy (as we have an open system) for both states, being the inlet, state 1 and the outlet, state 2. We will know these values by checking the vapor charts of R134a, I used the ones found in Thermodynamics of Cengel, 7th edition.
Then, our values are:

Now we proceed to know the work with the following expression:

Now we replace values and our result is:

(b)
To know the volume rate at the compressor inlet, we need to know the specific volume in that phase, as we have that is saturated and at -24°C, we can read our table:

With our specific volume and the mass rate, we can calculate the volume rate:
