Answer:
ΔV = -0.97 m³/ kg
ΔH = 0 kJ/ kg
Explanation:
<u>To determine the change in the </u><u>specific volume</u><u> we need to </u><u>use the ideal gas law</u><u>:</u>
<em>where</em><em> P</em><em>: </em><em>pressure </em><em>of the gas </em><em>V</em><em>: </em><em>volume </em><em>of the gas, </em><em>R</em><em>: i</em><em>deal gas constant</em><em>= 0.4119 kJ/kg.K = 0.4119 kPa.m³/kg.K and </em><em>T</em><em>: </em><em>temperature </em><em>of the gas.</em>
<u />
<u>The </u><u>V₁,</u><u> at a compressed pressure is:</u>


<u>Similarly, the </u><u>V₂</u><u> is:</u>


Now, the change in the specific volume because the compressor is:

Finally, to calculate the change in the specific enthalpy, we need to remember that neon is an ideal gas and that is an isothermal process:
Have a nice day!
C. They all transfer energy
To solve this problem we will apply the concepts related to the calculation of power, from the two electrical forms:


Here,
V = Voltage
I = Current
R= Resistance
P = Power
PART A)

Replacing,


Resistance of bulb is 
PART B)



The bulb will draw 1.25A current
Surface tension<span> is a property of the surface of a liquid that allows it to resist an external force. for example, some objects can float on the surface of water, even though they are denser than water, and in the ability of some insectsto run on the water surface. This property is caused by cohesion of similar molecules, and is responsible for many of the behaviors of liquids.</span>
Frequency refers to how often something happens. Period refers to the time it takes something to happen. Frequency is a rate quantity. Period is a time quantity. Frequency is the cycles/second
