America Public University Chemistry Beyond Labz Specific Heat of Metal Lab Report.
Beyond Labz Heat Capacity
In this simulation you will collect look at the energy transfer that happens when a known mass of hot metal is introduced into a calorimeter containing a known mass of water. By measuring the initial temperature of the water and metal, and measuring the final temperature of the water and metal after they reach thermal equilibrium, you will be able to use q = m.c.
T and the concept of heat transfer in an isolated system, qwater + qmetal = 0, to calculate the specific heat capacity of the metal (cmetal) and compare it to the accepted value for the metal examined.
As a basis for understanding this lab you should read Chapter 5, section 5-2. You can also refer to Module 5 section on Energy, Heat Transfer and Specific Heat Capacity
Beyond Labz Instructions
Download the. Print this worksheet so that you can follow the directions on what to do, fill it in and submit it. (Please use this worksheet from Canvas instead of looking in the Beyond Labz software.)
Now launch the Beyond Labz software, and open the Chemistry Lab.
To launch the simulation look at the list of worksheets on the bottom left of the window. Click “Thermodynamics” and then select “Specific Heat of Pb”. The lab will then open.
Follow the instructions in the worksheet. It is a good idea to read through the entire worksheet first before you begin so that you are aware of what is expected. Also check the notes on worksheet and calculations below.
As you progress through the simulation, fill in data and observations on the worksheet in blue or black ink. No pencil! Even though this is a virtual lab this is good lab practice and also important to make sure your submitted work will be clear enough to grade.
To help you get started you can watch a short prelab demo of Beyond Labz that I made as aor video
Notes on worksheet and calculations
- For calculation (sig. fig) purposes the volume of water in the calorimeter is 100.0 mL
- For calculation (sig. fig) purposes, the initial temperature of metal = 200.0
- In step 6 and step 8, follow thermodynamic conventions and always calculate
T = Tfinal – Tinitial
- Remember that the unit J/g.K is the same as J/g.
- For help with calculating the specific heat capacity of the metal refer to Module 5 section on Energy, Heat Transfer and Specific Heat Capacity or refer to this
- The value of specific heat capacity must always be greater than zero. If you get a negative number you have made an error somewhere in your calculations or made an error in assessing the sign of qmetal or qwater
- Be careful assessing significant figures. Pay careful attention to the effect of subtraction to calculate
T on the overall significant figure of your answer.
Preparing and submitting your work
After you complete the worksheet, take a picture of each completed page or scan them. Make sure the quality is good enough to view clearly. If I cannot read it, I will not grade it.
It is best to submit as a PDF or .jpeg (jpg) file. You can submit one file for each page or combine them into one file.
It is best if you submit one file for each simulation.
