Topic > Essay on thermochemistry - 1328

Educational purpose - "I wonder..." Statements - Guided reading Educational purpose: Students must understand the importance of thermochemistry. Thermochemistry revolves around the energy (heat) associated with reactions and other materials. This field of chemistry has a variety of terms and applications that must be understood before taking college-level chemistry courses. Terms such as temperature, specific heat, calorimeter, and enthalpy are commonly used in laboratory experiments. These terms also connect to common elements that students may see on a daily basis. Warm hands and the number of calories in foods are related to thermochemistry. What two places can cause students difficulty while reading? The introduction of the specific term Have any of you wondered what the magic happens inside a warm hand? The hot hand is a small bag that contains mysterious elements that combine to start a reaction that produces heat. There is a specific field of chemistry that studies the heat associated with reactions and today we begin our journey to discover this form of chemistry called thermochemistry! Thermochemistry is a fascinating field of chemistry that contains new terms and ideas that must be understood in order to proceed to mathematical applications of thermochemistry. We will create “I wonder…” statements to make it easier to learn these new terms as we read the book. So let's say I read the section on heat and temperature. I learned that heat and temperature are related, but they are different quantities. This idea of ​​difference makes me think about how the two terms are related but different, so I began writing a statement that embraces my curiosity about these terms and will hopefully be answered in the text or through a class discussion. I wonder... how heat and temperature are integrated into chemistry. I will now go ahead and read the next section of the text to hopefully answer my statement. So as I was reading I came across the term “specific heat” and the definition stated that specific heat is the amount of energy needed to raise the temperature of one gram of a substance by one degree centigrade or one kelvin. I learned that specific heat is a value needed to increase the temperature of one gram by one degree! Since I found my answer in the text, I will write this definition in my statement, so I can discuss it later
