It's a term meaning being baptised in water. Being baptised is also called going into the liquid grave because it symbolizes dying and then being rose up in the day of ressurection or when Jesus comes back to Earth to gather up his children. Baptismal water can also be poured or sprinkled, in which case the symbolism is of washing. There is a debate between Christians as to which of the methods is the Biblical one.
The baptismal font.
A Font is a basin or pool containing water for the baptism (ritual washing) of new members. Its size depends upon the particular baptism rite practiced by the church. It may be a small bowl containing water that is poured on the head; or it may be the size of a small swimming pool, and used for totally immersing an older child or adult.
The water will be subject to evaporation by wind and heat from the sun. Eventually, the vessel containing the water will dry out.
Presumably you are referring to baptismal fonts

A small basin. Usually in the front of a Catholic or a different denomination of a Christian church that believes in water baptism for infants. Note: to the best of my knowledge, Protestants believe in dedicating services so this is not used. They believe that after a person comes to the age of concent that a full baptism immersion baptism is done.
The Baptism Pool holds the water that will be used for the Baptism.
A precise answer would require knowing the ambient temperature, the temperature of the water at the start, and the conductive properties of the vessel containing the water.
