Teacher:Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.
Teacher: Now, understand the problem? Solve this instance: CONTEXT: Marshmallows expand so much because the water in them becomes steam, and gas takes up a LOT more volume than liquid. Specifically, 1 mL of water becomes ~1.36 LITERS of vapor, before it gets heated further. That's 1000-fold expansion, before you add additional expansion as the gas is heated. Marshmallows don't have all that much water content, but when it's trapped in a stretchy gelatin matrix that holds gas readily, it only takes a bit to blow the whole thing up like a balloon.You are correct that the gas expansion on its own is insufficient; unless I've badly muddled my calculations, gas expansion from 20C to ~150C (caramelization temperature) will increase the gas volume by under 50%.  <sep>  Q: Why do marshmallow get so puffed up in the microwave? A: Marshmallows expand so much because the water in them becomes steam, and gas takes up a LOT more volume than liquid  Q: How big can they get? A: 1 mL of water becomes ~1.36 LITERS of vapor 
Student:
Do they ever get so big they explode?
