This experiment was the fire syringe. We put a little cotton into the inside of cylinder and pressed the plunger quickly. We found fire. At this activity, we should calculate the final temperature in the cylinder. Before approximating the final temperature of air in the syringe, we should knew the initial length if air column, final length of air column, inner radius of the tube, initial volume, finial volume, and initial temperature.
We used the calipers to measure the inner radius of the tube. The initial temperature is room temperature.
This picture showed all quantities that we need measure and calculate.
