Heat can be diverted away from the area you want to cool using the refrigeration cycle, also known as a heat pump cycle. This is done by repeatedly compressing and expanding the working refrigerant (air, water, synthetic refrigerants, etc.) to change its pressure.
<h3>What is the cycle of a heat pump?</h3>
- In order to heat the air within a building, a heat pump warms the air outside by drawing heat from it and adding it to it. The following procedure is used to achieve this: A gas is created when liquid refrigerant absorbs heat from the ambient air in the "evaporator."
- The pressure buildup from the compressor raises the temperature of the refrigerant, just like it does with everything that is put under pressure. The refrigerant is a heated vapor, ranging in temperature from 120° to 140°F, when it exits the compressor.
- The chemical refrigerant, once transformed from a gas to a liquid state, has a remarkable capacity to absorb heat. The heat inside your house might be absorbed and released outside when the refrigerant undergoes a state shift as a result of compression and pressurization.

Explanation:
here you go. the answer is 303x+4
Answer:
Option 2.
Explanation:
A turbine produces mechanical work at the expense of fluid energy, that is to say according to the First Law of the Thermodynamics:
The conditions at inlet and outlet are, respectively:
Inlet - Option 1 (Superheated Steam)
Inlet - Option 2 (Superheated Steam)
Outlet (Superheated Steam)
The mechanical work per unit mass of each option is determined hereafter:
The second option offers more mechanical work per unit mass.
Answer:
3.99 mm
Explanation:
To treat a diffusive process in function of time and distance we need to solve 2nd Ficks Law. This a partial differential equation, with certain condition the solution looks like this:
Where Cs is the concentration in the surface of the solid
Cx is the concentration at certain deep X
Co is the initial concentration of solute in the solid
and erf is the error function
First we need to solve the Cs-Cx/Cs-Co on the left to search the corresponding value later on a table.
We look on a table and we see for erf(z)=0.4284 z=0.40
Then we solve for x
