Through detailed explanations, visual aids, and practical examples, this material covers the fundamental concepts of azeotropic and extractive distillation, including the flowsheet of azeotropic distillation columns, the role of entrainers, and the challenges posed by azeotropes in traditional distillation processes.   

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Blue Coral Periodic Table is your quick guide to all 118 elements. Swipe and tap your way across the table for quick stats on each element. Dive deeper and recolor the table with patterns based off properties such as boiling point, melting point, and atomic radius.

View the atomic model for each element and see how the electron configuration changes as you move from element to element.

Blue Coral Periodic Table is fully responsive in the web browser for large and small devices in both horizontal and vertical orientations.

Students investigate the property dependence between concentrations and boiling point. In section 1, students first investigate the boiling point of various liquid solutions. In section 2, they analyze data collected by the entire class to generate two boiling point curves, one for salt solutions and one for sugar solutions. Finally, in section 3, students use the data they have analyzed to determine how to create a solution that has a particular boiling point and is a cost-effective design.

Students will create their own barometer in this activity and use it to discover atmospheric pressure and its relationship to the boiling points of liquids.

This lesson focuses on how food packages are designed and made. Students will learn three of the main functions of a food package. They will learn what is necessary of the design and materials of a package to keep food clean, protect or aid in the physical and chemical changes that can take place in a food, and identify a food appealingly. Then, in the associated activity, the students will have the opportunity to become packaging engineers by designing and building their own food package for a particular type of food.

Student groups are challenged to create food packages for specific foods. They focus on three components in the design of their food packages; the packages must keep the food clean, protect or aid in the physical and chemical changes that can take place in the food, and present the food appealingly. They design their packaging to meet these requirements.

This is a hands-on lab activity about the properties and states of water. Learners will complete activities using different liquids to understand the three states of matter, explain how the high heat capacity and abundance of liquid water makes life on Earth possible, and understand that water containing salts and minerals has different properties than fresh water. They will graph data to analyze and articulate results and conclusions. The lab is set up as three stations that small groups of students rotate through; it can also be done as demonstrations (e.g., for younger students). Background information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities.
