Beyond Labz Heat of Fusion of Water

Beyond Labz Heat of Fusion of Water.

I’m studying for my Chemistry class and need an explanation.

Beyond Labz Heat of Fusion of Water

In this simulation you will measure the energy transfer that happens when a known mass of ice melts in a calorimeter containing water. By measuring the initial temperature of the water and ice, and measuring the final temperature of the water after they reach thermal equilibrium, you will be able to use q= m.LaTeX: Delta

Δ
Hfusion for heat transfer of change of state, and q = m.c.LaTeX: Delta

Δ
T for heat transfer of warming/cooling, and the concept of heat transfer in an isolated system, q1 + q2 … = 0, to calculate the heat of fusion of water (LaTeX: Delta

Δ
Hfusion) and compare your experimentally determined value to the accepted value.

Beyond Labz Instructions

Download the Beyond Labz worksheet for Heat of Fusion of Water. 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.)

  • Please download and view the worksheet using Acrobat Reader for best results. You may see font errors using the Canvas preview button or other PDF viewers.
  • For step 3, the text should read “100.0 mL of water is already in the coffee cup. Use the density of water at 25.00 LaTeX: ^circ

    C (0.998 g/mL) to…”

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 “Colligative Properties” and then select “Heat of Fusion of Water”. 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 the 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 a narrated powerpoint presentation or videoPlay media comment.

Notes on worksheet and how to do calculations

  • For calculation (sig. fig) purposes the volume of water in the calorimeter is 100.0 mL
  • Please watch this narrated powerpoint presentation for guidance on how to calculate the heat of fusion of water in kJ/mol (step 7 of worksheet)
  • Show your work for calculations for full credit.

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.
