Question

whyhot water bottles are very efficient for fermentation

Answer 1

Water has the highest specific heat capacity,therefore,it takes a time to heat and a long time to cool. This is the reason why hot water bottles are used for fomentation,as the water remains hot in the bottle for a long time in spite if giving off large quantities of heat.

Answer 2

Answer:

Hot water bottles are used for fomentation. The reason is that water does not cool quickly due to its high specific heat capacity, so a hot water bottle provides more heat energy for fomentation over a longer period.
