Left a little plastic togo container of salsa out for a couple days. It started to bubble, also making a gas that poofed out the plastic lid. When I held it to throw it, it wasn’t hot, tho it was bubbling away. Why didn’t it feel hot?
That’s gas in the salsa being released, mostlikely your salsa has gone bad. The cold is probably because: A it’s not room temperature and glass and metal containers usually are colder. B- if it got cold after opening it and you heard a gas leaving sound, then that’s expansion.
