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

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
