Background Paper Have you ever been sitting there and just wondered about various things dealing

The study of science is Physics. Physics means the natural science which involves the study of things made up atoms or matter, and along with related concepts such as energy and force. The experiment is Physics because we are using heat from the sun, and transferring the heat to the oven. So heat or thermal energy is the measure of the amount of energy that is contained in a material. Heat depends on how much of the material, which would be sunlight, you have: if you have twice the amount then normal of whatever you are testing, then you have to double the amount of heat you have. “Temperature is a measure of the ability of a substance, or more generally of any living or nonliving subject, to move the energy made of heat to another living or nonliving subject.” “But we need to remember that light slows down has it goes farther from the sun, and bends toward the normal and has a shorter wavelength when it enters a higher value medium (A substance that makes it possible for the energy to move to one location to another)”. “ Also a light wave is transverse (they can be polarized).”

This information has massively help to answer by explain the difference between endothermic and exothermic in common language which also helped me know why an exothermic reaction can be used to heat food but an endothermic reaction cannot.

Calorimetry is the science of measuring the change in heat absorbed or released during a chemical reaction. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. The device used to measure calorimetry is a calorimeter. A calorimeter can range from very expensive lab ones to coffee styrofoam cups but they are all tightly sealed in order to prevent heat from escaping.

Thermodynamics is “the study of the effects of work, heat, and energy on a system”. In Thermodynamics to find the temperature change I will use the formula: Q=MCT. In this formula Q represents the heat added, M is the mass, C is the specific heat, and Tis the change in temperature. From using this equation I will later figure out the uncertainties I have in this experiment using the formula: Amount of DataGiven (average data/ amount of data given) then you take the given and subtract it from the answer from the formula above, lastly you add it up and square root it. Next, you put it in this form: average data ± answer using the formula above. Lastly, I will use error bars on the graphs to represent the uncertainty of the graphs. Error bars are represented by this image:

You have the mass of water from calculation #9, the specific heat of water is 4.184 J/g(oC), and the temperature change of water

In this experiment you will observe some physical and some chemical changes. You will observe that energy must be used to start some chemical reactions, and that it is produced in others.

direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate

The first part of this lab’s objective was to find the calorimeter constant using DI water. We accomplished this by first checking the temperature and then adding 20 mL of cold DI water into our calorimeter. Next we collected 20 more mL of DI water in a 50 mL beaker and placed it onto a burner in order to heat it. We removed the beaker once the temperature of the water reached 60º celsius. After we removed the water, we poured it into the calorimeter with the cold water and took the temperature. The temperature ended up being 37º celsius. From this information we were able to calculate for qhot, qcold, qcal and Ccal. To be as accurate as possible we conducted this same test three more times and used the averages from all Ccal calculations as the final Ccal.

Mass of water x 4.2 (water’s specific heat capacity) x temperature change = energy transferred from the fuel to the water

Introduction: The theory behind this experiment is the heat of a reaction (∆E) plus the work (W) done by a reaction is equal to

Heat is a form of energy that is transferred between two substances at different temperatures. The flow of the energy is from the object of higher temperature to the object of lower temperature. The heat is measured in units of energy, usually calories or joules. Temperature on the other hand, is how cold or hot an object is. The temperature is the average kinetic energy per molecule of a substance. This is measured in degrees on the Celsius or Fahrenheit or in Kelvins.

Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation.

Purpose: This lab taught procedures for determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical reaction. Much of the energy people depend on comes from chemical reactions. For example, energy can be obtained by burning fuel, metabolizing of food or discharging a batter.

Abstract—The disciplines of physics, biology, and chemistry have adopted highly diverse approaches and strategies on thermodynamics education. Many studies have addressed the problems in making the students understand the fundamentals in thermodynamics. Students tend to memorize the equations without the knowledge of their applications and therefore forget them soon after their exams. This paper talks about the challenges of teaching thermodynamics course to biotechnology students. It also highlights some of the teaching learning methods adopted in some universities in order to make the students develop interest and understand the role of thermodynamics in biotechnology. The course outcomes attainment for the thermodynamics in department of biotechnology, BMS college of Engineering, has also been compared for the last two academic years. A social learning platform called “Wiksate” has been introduced at the institution level, where thermodynamics has been chosen as the course from department of biotechnology, to see if it helps the students easily learn the basics of thermodynamics.
