Question

If a piece of bread is placed under a bell jar it gets mould what would happen if the bread was not covered by the bell jar

Answer 1

the mould would grow even faster...as when the bread is covered by the bell jar...there develops warmth inside the bell jar which prevents the growth of mould to sone extent but when the bread is kept in open it gets all conditions necesaary for the growth of mould.......so the mould will grow even faster
