A weather balloon is inflated to a volume of 26.9 L at a pressure of 734 mmHg and a temperature of 30.0 ∘C. The balloon rises in the atmosphere to an altitude where the pressure is 390. mmHg and the temperature is -14.3 ∘C.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

i think that the answer is c

the correct answer would be b) volume versus temperature, because they are also directly proportional.
