Aweather balloon is inflated to a volume of 28.1 l at a pressure of 745 mmhg and a temperature of 29.0 ∘c. the balloon rises in the atmosphere to an altitude where the pressure is 380. mmhg and the temperature is -16.3 ∘c. assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

Explanation:

For these changes in pressure and temperature, assuming that the gases in the balloon are ideal, we can apply the general equation of gases:

Been 1 the initial conditions and 2 the final ones:

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
