Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility

1. What physical evidence did you find at the victim’s home? Matches‚ Natalie’s ID‚ burned floor‚ and space heater. 2. Describe the process that you used to take a sample of the puddle-shaped burn pattern on the floor. Why did you also take samples from the portion of the floor that was not burned? I used a chisel to scrape up some wood and then used tweezers to pick it up and put it in an airtight container. I would take samples from none burned wood to compare the results in testing. 3. What
