Question

Two identical balloons are filled to the same volume, one with air and one with helium. The next day, the volume of the air-filled balloon has decreased by 4.7 %. By what percent has the volume of the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the temperature did not change.) Express your answer using two significant figures. fHe = %

Step 1

Given that the volume of the air-filled balloon has decreased by 4.7%, we can calculate the new volume as follows: New Volume = Original Volume - (4.7% of Original Volume) Let's denote the original volume as V. New Volume = V - 0.047V New Volume = 0.953V Show more…

Two identical balloons are filled to the same volume - one with air and one with helium. The next day, the volume of the air-filled balloon has decreased by 4.7%. By what percent has the volume of the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the temperature did not change). Express your answer using two significant figures.
