Aballoon is filled to a volume of 2.20l at a temperature of 22*c. the balloon is then heated to a temperature of 71*c. find the new volume of the balloon

At constant pressure, the volume of an ideal gas is directly proportional to the absolute temperature. The new volume of the balloon is 2.565 L.

Charles law:

At constant pressure, the volume of an ideal gas is directly proportional to the absolute temperature.

Where,    

T1 - initial temperature = 22+273.15= 295.15 K  

T2 - Final temperature = 71+273.15= 344.15 K  

V1 - initial volume = 2.20 L

V2 - final volume  =?

Put the values in the formula ,

2.20 / 295.15 = V2 / 344.15  

V2 = 0.00745 x 344.15

V2  = 2.565 L  

Therefore, the new volume of the balloon is 2.565 L.

2.565L

Explanation:

         V1/T1=V2/T2        

          Unit of Kelvin = 273.15

          T1= 22+273.15= 295.15 K

          T2 = 71+273.15= 344.15 K

          V1 = 2.20 L

          V2 =?

          2.20/295.15=V2/344.15

          0.00745 x 344.15 = 2.565 L

Hence,  2.565 L is the new volume of the balloon.
