Homework Help: physics

Posted by conrado sanchez on Wednesday, November 16, 2011 at 2:10am.

Because of the pressure inside a popcorn kernel, water does not vaporize at 100C. Instead, it stays liquid until its temperature is about 175C, at which point the kernel ruptures and the superheated water turns into steam. How much energy is needed to pop 95.0 g of corn if 12 percent of a kernel's mass consists of water: Assume that the latent heat of vaporization of water at 175C is 0.90 times its value at 100C and that the kernels have an initial temperature of 175C.
