Introduction

In this experiment you will investigate the insulation properties of three different coffee containers. You will measure the insulation properties of each cup over by using temperature probes. This type of real world product testing would be of special interest to coffee shop owners, who would like to figure out which cup insulates the best with the lowest cost.

In the experiment, you will fill each cup with equal amounts of hot water and leave them on the table to cool. Using LabVIEW you log the temperature of the cups while they were cooling, with data points of the three cups taken every ten seconds. You will be able to compare their performance and make a decision on which cups you would buy.
