When a substance changes state from a liquid to a vapor, the process occurs at a constant temperature. When this occurs in a refrigeration system, it is said that the refrigerant is “saturated”. For water, experiments have proven that saturation, or boiling, occurs at 212ºF at 14.7 psia, which is atmospheric pressure. However, if someone were […]

“Saturation” is a term used to describe a substance that is at its boiling point. Water, for example, is said to be saturated when its temperature is 212ºF at sea level. The 212ºF water may be a liquid, a vapor, or a mixture of the two. When a substance is saturated, heat added or removed […]
Ammonia Set Sail in this week’s edition of the Ammonia Week in Review… Five Workers Hospitalised By Ammonia Gas Leak In Palghar Amul Plant – The incident took place at the plant located at Kaner Phata when workers were carrying out routine maintenance of the refrigeration system, said an official.

To reinforce what is known about the states of matter, it can be helpful to study the heat energy profile of water. The graph below shows heat, measured in BTUs, applied to a pound of water on the horizontal axis and the temperature change of the water on the vertical axis. The values displayed are […]
