Hop to it with Science Comics: Frogs, the next volume of First Second's middle-grade nonfiction series!Every volume of Science Comics offers a complete introduction to a particular topic—dinosaurs, the solar system, volcanoes, bats, robots, and more. Whether you're a fourth grader doing a natural science unit at school or a thirty-year-old with a secret passion for airplanes, these books are for you!With their signature sounds, athletic tongues, and bulging eyes, there’s a lot to love about frogs! But did you know that they soak up air and even liquid through their skin? Or that they use their eyes to swallow food?

So pull up a lily pad and dive in, because the frog facts in this book will truly give you something to croak about!
'Chemical engineering is the field of applied science that employs physical, chemical, and biological rate processes for the betterment of humanity'. This opening sentence of Chapter 1 has been the underlying paradigm of chemical engineering. Chemical Engineering: An Introduction is designed to enable the student to explore the activities in which a modern chemical engineer is involved by focusing on mass and energy balances in liquid-phase processes. Problems explored include the design of a feedback level controller, membrane separation, hemodialysis, optimal design of a process with chemical reaction and separation, washout in a bioreactor, kinetic and mass transfer limits in a two-phase reactor, and the use of the membrane reactor to overcome equilibrium limits on conversion. Mathematics is employed as a language at the most elementary level. Professor Morton M. Denn incorporates design meaningfully; the design and analysis problems are realistic in format and scope.
