Ahot air balloon is filled to a volume of 44.5 l at 758 torr.
what will be the volume of the balloon if the pressure decreases to 748 torr under constant temperature?
a. 45.1 l
b. 43.9 l
c. 44.5 l
d. 49.0 l

The volume of the balloon, if the pressure decreases to 748 torr, will be 45.1 L

Explanation:

Step 1: Data given

Volume of the balloon = 44.5 L

Pressure in the balloon = 758 torr

Final pressure = 748 torr

Step 2: Calculate final volume

P1*V1 = P2*V2

⇒ with P1 = the initial pressure = 758 torr

⇒ with V1 = the initial volume = 44.5 L

⇒ with P2 = the final pressure = 748 torr

⇒ with V2 = the final volume = TO BE DETERMINED

V2 = (P1*V1)/P2

V2 = (758 * 44.5) /748

V2 = 45.1 L

The volume of the balloon, if the pressure decreases to 748 torr, will be 45.1 L
