Task id11976
The shell of the balloon is partially filled with helium, therefore, when rising in the earth's atmosphere, the gas pressure inside the balloon is always equal to the external atmospheric pressure. The ascent occurs slowly, so the temperature of the gas in the balloon is the same as the temperature of the atmospheric air. How does the lifting force of a balloon change with altitude if the temperature decreases linearly with increasing altitude?
