If the bread is colder at the start, the toaster will have to heat it a little longer to get it up to ideal toasting temperature, but it will have no trouble getting there. The coils will get hot, and then the bread will get hot, too. From the toaster's point of view, a 20- or 40-degree change in starting temperature hardly matters. The toaster needs to heat its coils from room temperature to somewhere over 600☌. and the heating element in a toaster is 900 K. If we switch to Kelvin, which counts in degrees above absolute zero, a freezer is 260 K, a fridge is 275 K, a normal room is 295 K. But the "zero" on the Celsius scale is just a point chosen by convention. The zero on our usual temperature scales can confuse things, since it makes it seem like going from 10° to 20° is "doubling" the temperature. Since the toaster is operating at such high temperatures, it would hardly notice whether the surrounding environment is 20☌ (room temperature), 4☌ (a fridge), or -15☌ (a freezer). The coils in regular toasters get hot enough to glow, which means they're over about 600☌. But toasters heat things up a lot more than freezers cool them down. It's easy to think of a toaster and freezer as equivalent-one cools things down and the other warms them up. But if you say "it would get cold," then the toaster hasn't done its job.įor starters, the answer: The toaster would win. What even happens, right? Because if your answer is, "it would get hot," then the freezer hasn't done its job.
Griffin sums up the situation like this: You put a toaster in a freezer.
(A quick safety note: If you actually do this, keep in mind that the toaster may melt some of the ice in the freezer, leaving you with a running electrical appliance in a pool of water.) Since they don't really settle on a final answer, I thought we could help them out by taking a closer look at the physics of freezer toasters. They have a fun discussion of a few aspects of the problem before eventually moving on to the next question. (The discussion comes around the 36-minute mark.) On a recent episode of Justin, Travis, and Griffin McElroy's terrific advice podcast, My Brother, My Brother and Me, the brothers pondered a Yahoo Answers question about what would happen if you put a toaster inside a freezer.
