Covalent Bonding
Heat Retention Graphing Lab
Background:
In class, you have learned that covalent bonds have low boiling points, low melting points, and that they are brittle when
in the solid state. Mr. Haidinger placed water in a pot and peanut oil in another pot. He heated both on his stove at the
same temperature for 10 minutes. Below you will find the data for the temperatures of both water and oil. You will use
this data to create a formal analysis and conclusion section of a lab write up.

Graph:
Create ONE line graph of the data using graph paper and a ruler. Place time on the x-axis and temperature on the y-axis.
Time is the independent variable and temperature is the dependent variable. Dependent variables are always placed on
the x-axis and independent variables are always placed on the y-axis.
Analysis and Conclusion
Create an analysis and a conclusion section based on the data and your graph. Use the guidelines from “How to Write a
Formal Lab Write Up” to help you complete these sections.
