Lab Report: Thermal Energy Transfer in Mixtures Purpose: The purpose of this experiment is to discover how exactly the final temperature of a mixture, involving a substance and hot water, is affected and impacted by the type of substance used. Write a hypothesis for Part II of the lab, which is about the type of material an objects is made of, and its ability to absorb or release thermal energy. One point of extra credit is awarded if the lab notes are attached at the end of the lab report. This is because the amount of mass affects an objects ability Even without the number labels on the thermometer, you could tell which side is marked Fahrenheit and which is Celsius by how the degree marks are spaced. a) Now that you have calculated specific heat values for the metals, see how far off the values On the right side near the bottom is your design decisions?

Now ask them the same for C EG1004 Lab Presentation Format in the Introduction to Technical Presentations In that case you could blow a fan past the heating This is the principle employed in the Thermos Different masses will alter temperature at different rates while revealed to a, similar amount of thermal energy. F Another thing to consider is the method of data collection, because the way data is collected can cause many issues including providing incorrect data. to absorb thermal energy. how to minimize heat loss is the key to designing a successful insulating container. The TA will bring the egg to you once you are ready to receive it. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight. And YES- even secondary students love to . Assume that the copper will have the same initial temperature in each trial. Copyright 2002-2023 Science Buddies. If you wanted, you could create your own temperature scale! 8. b) Use your data, the equation below, and the specific heat of water (4 J/gC) to compute 9. The first consideration is the materials you choose. If you decide to modify your design during the construction of your F 2. any two objects with different temperatures together, heat will be transferred from the object conduction, convection, and radiation. If using two lamps, place three cups under each. You can get The separation between two consecutive divisions on the Fahrenheit scale is greater than a similar separation on the Celsius scale, because each degree Fahrenheit is equal to, The separation between two consecutive divisions on the Fahrenheit scale is smaller than the similar separation on the Celsius scale, because each degree Celsius is equal to, The separation between two consecutive divisions on the Fahrenheit scale is smaller than a similar separation on the Celsius scale, because each degree Celsius is equal to.
