As Pressure Increases Temperature Increases

PRESSURE AND TEMPERATURE RELATIONSHIP

METEOROLOGIST JEFF HABY
In a closed system where book is held constant, there is a direct relationship between Force per unit area and Temperature. In a straight human relationship, 1 variable follows the aforementioned change when it comes to increasing and decreasing. For example, when the pressure increases then the temperature besides increases. When the force per unit area decreases, then the temperature decreases.
In that location are 2 examples that demonstrate this principle. The get-go is that of a spray can. The volume of the can is constant. When contents are removed from the tin, then the mass of the contents will be reduced in the tin can. Because there is less mass in the can with a abiding volume, the pressure level will decrease. This pressure decrease in the can results in a temperature subtract. The contents coming out of the can too cool in temperature but for another reason. Outside of the can the volume is not held constant. Thus the contents are gratuitous to expand when they motion from the loftier pressure in the can to the low pressure exterior of the can. Expansional cooling causes the contents coming out of the tin to absurd. This effect can be noticed in spray-on deodorants.

In the 2nd instance, a compressor is shown. This is used in appliances such as refrigerators. The refrigerant air is pressurized into the compressor meaning the pressure increases as more than air is squeezed into the aforementioned book. This causes a temperature increase. With time, this heat is lost to the surroundings through coils. Additional heat is given off as the refrigerant releases latent heat past turning from a gas to a liquid as it cools. The compressor volition exist location is a position such as the dorsum of the refrigerator. Thus, the outside portion of the refrigerator can give off oestrus to the air due to this process. The high pressure level liquid in the compressor is then transferred to the inside of the refrigerator and gradually released. This results in a procedure similar to the first instance with the addition of latent rut cooling that takes places every bit the refrigerant changes phase from a liquid to a gas. The rapidly expanding air cools and this causes the temperature to decrease inside the refrigerator and freezer due to the very cold coils being in contact with the surrounding air inside the refrigerator.
