Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus), but having different numbers of neutrons. Most (66 of 94) naturally occurring elements have more than one stable isotope. Thus, for example, there are three main isotopes of carbon.
According to Nestle, the parent company of Hot Pockets, a frozen Hot Pockets Cheeseburger sandwich should cook for 2 minutes in a 1100 watt microwave oven. A refrigerated sandwich cooks for 1 minute. In a 700 watt microwave oven, a frozen Hot Pockets Cheeseburger sandwich cooks for 2 minutes 15 seconds.
Hot Pockets are designed to be frozen and most food will last about 2 to 3 months and still be good. Check the date on the package and figure about 3 months from that. But whatever you do, do not thaw and re-freeze as it will be no good when cooked. Login or Sign Up to answer this question.
