When you 'pop' popcorn, you are essentially conducting an experiment using Gay- Lussac's Law (there are a couple of other things going on here, too, but let's just focus on the gas laws). There is a fixed number of moles of air and water inside a kernel. As you heat the air and water, water turns to a gas, and the pressure inside the kernel increases until the kernel 'pops'. If the initial pressure inside the kernel is 745 mmHg at a temperature of 20C, find the pressure inside the kernel at a temperature of 120C. (Treat this problem as if the air and water inside the kernel are all in gas form and behave like ideal gases).
