In this experiment, you will be using a “coffee cup” calorimeter to measure the rate of heat loss for several substances and determining which of the substances is the best insulator. You will be testing the insulating capabilities of three types of fabric and the control will be air. The three types of fabric are: Test Sample 1: 52% cotton/48% poly fabric Test Sample 2: 100% acrylic fabric Test Sample 3: 80% cotton/20% poly fabric For the control, and each test sample, you will be measuring the amount of heat lost by the water in the calorimeter over 6 minutes, taking the temperature every 30 seconds. Be sure to record your data on your data sheet . View the animation to complete this experiment.
