what is the area required to model Venus' atmospheric pressure if we specify that the atmospheric pressure on Earth (~1 bar) corresponds to 1 person each occupying about 1 m 2 (e.g., 9 floor tiles). Higher pressures should correspond to more atoms per unit area (so a pressure of 10 bars might be represented by 1 model with 1 person in an individual floor tile). Can all planets be modeled in the classroom when the classroom is 24 feet of 7.3 meters in length showing the calculations
