EXPERIMENT: MASS OF GAS We often do not think of gas in terms of having mass. The atmosphere is something we live in and breathe. In this experiment, we will investigate whether gas does truly have mass. Hypothesis: If gas does indeed have mass, then different volumes of it will have different masses. This could be demonstrated by using a simple balance and comparing the two different volumes, captured by means of balloons. Online Lab Watch the animation and use your observations to answer the questions. 00:5100:51 SHOW TRANSCRIPT Answer the following questions. Did the different sized suspended balloons balance? If they did not, which balloon tipped the scale down? Did your results validate the hypothesis above? Give an explanation for your results, including a discussion of how the data collected either validated, or disproved the hypothesis.
