## valiyuh 11 months ago A 600mL balloon is filled with helium at 700mm Hg barometric pressure. The balloon is released and climbs to an altitude where the barometric pressure is 400mm Hg. What will the volume of the balloon be if, during the ascent, the temperature drops from 24 to 5ºC?

Use the combined gas law to solve for V$$_2$$, when you have: $$\sf \color{red}{\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}}$$
