Investigation of heat capacity and specific heat using different temperatures of water and solids hp gas online booking no


Students will be introduced to the concept of heat capacity and specific heat after they have already been taught and/or exposed to the concept of chemical reactions, endothermic/exothermic reactions, and the law of conservation of energy. The purpose is for the students to understand the transfer of heat from one location to another and that the specific heat of water does not change, regardless of temperature. The introduction of the lesson will start with a question, drawing out information from students’ prior knowledge. The students will discuss why a lake or an outdoor swimming pool becomes cooler in the morning, despite being warmer the day before in the afternoon or evening. They will discuss with partners, journal their ideas, and then share with the entire class. Once this occurs, students will be taught concepts related to specific heat and heat capacity. They will learn the terminology, reminded of law of conservation of heat and exothermic/endothermic reactions. After learning the topic, they will do the activity "Heat Capacity," using materials listed below. Procedure is also included.

-Just before doing the experiments, fill a third bucket with water and ice, and into the ice water add all the other components the instructor provides with any liquids in their bottles. Allow all to come to thermal equilibrium in the ice/water.

4) Using terminology learned in this class (heat capacity, specific heat, law of conservation of energy), write a paragraph conclusion about your observations and what you have learned in this experiment. Include any questions that were generated during the experiments and what you may possibly do to change the experiment if you did this again.

You’ve just taken a class on energy conservation and you want to do your part. You realize that you can save a lot of energy (and even some money) by turning your water heater down to between 50 and 55 ºC. However, your water heater doesn’t have a calibrated control (most don’t) and, to make matters worse, your thermometer only reads up to 40 ºC!

Students will need to create a lab report for the "Heat Capacity" lab, using their laboratory notebooks. They will be graded on components needed for the lab notebook such as title of lab, lab purpose (question to answer), materials needed for experiment, procedure that was followed, data collection, and conclusion to the lab. Teacher will lead students in a discussion and provide them with more background information after the lab, re-iterating information that should have been taught prior to the lab in a lecture/presentation form. After the lab, emphasis is made on topics now the students have been exposed to the activity. To assess final understanding the Mini-Lab "In Hot Water" will be used, with students working in pairs to problem-solve, using the knowledge they have obtained from the "Heat Capacity" lab. This final assessment will be graded based on student lab reports, which includes title, purpose of the lab, materials used, procedure that was followed to obtain data, data collection, and conclusion. Students will answer the questions provided in the Mini-Lab. Standards
