In a lithium bromide refrigeration system, what type of lithium bromide solution is capable of absorbing water vapor readily?

In a lithium bromide refrigeration system, a strong lithium bromide solution is capable of readily absorbing water vapor. This is because the strength of the solution refers to the concentration of lithium bromide in water. A stronger solution has a higher concentration of lithium bromide, which enhances its hygroscopic properties, allowing it to attract and absorb water vapor from the surrounding environment.

In practical terms, when water vapor enters the system, the strong solution has a greater affinity for the water molecules due to the high concentration of lithium bromide present. This absorption process is a crucial component of the refrigeration cycle in absorption systems, as it facilitates the cooling effect by removing heat from the evaporator side and transferring it to the refrigerant.

The other options represent solutions that are either too dilute or not concentrated enough to effectively absorb water vapor. A weak solution, for instance, would be less effective at this absorption due to lower lithium bromide content, while a concentrated solution may be at risk of crystallization and thus wouldn’t function effectively in the refrigeration process.
