Jelly can spoil. It can grow mold. If it does, throw it out. If it hasn't been processed or sealed properly or the sugar content is low, it can ferment. Throw out fermented jelly, too.
The best way to store unopened jelly is in a cool, dark, dry area. After opening, store it in the refrigerator.
It can grow mold if it is left unrefrigerated for a long time. But it is unlikely to spoil otherwise.
heat and light
A lid will keep the wax from possible getting broken and letting the jelly spoil. Does not have to be on the jar but I would recomend it.
because of there heat and gas and loses its moisture
the atoms in jelly heat up and turn into steamthat is a liquid that turnned into a gas.
because it has gas and the sun gives heat..............
Probably not, although it will be chilled.
the answer is turkey because when you leave out any kind of meat it will spoil but peanut butter takes longer to spoil.
Yes. It won't spoil. Jelly, Jam and preserves don't need refrigeration. People refrigerate them mostly to keep ants and bugs from getting into them.
While both have the potential to cuase nauseous feelings or food poisoning, butter is more likely to do so. Butter contains dairy, which can go rancid or spoil, especially if left in sunlight, near direct heat, or used after its expiration date. Jelly is often preserved both naturally and commerically, giving it a longer shelf life and more stable level of bacteria present.
Plastic is bad for compost because it throws the heat of in the pile and can cause a spot to spoil
I won't know why you want to microwave petroleum jelly, but I won't recommend it. If you heat it long enough, the jelly could melt and vaporize, and then has a chance of lighting/exploding from a spark from the microwave's electronic system.
