Question

A balloon 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

Answer 1

2.565L

Explanation:

• Charles law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.V/T=K

         V1/T1=V2/T2        

          Unit of Kelvin = 273.15

• To get the absolute temperature, we need to convert the degree celsius temperature to kelvin.

          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.

Answer 2

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.

$\bold {\dfrac {V_1}{T_1} = \dfrac {V_2}{T_2}} }$  

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.
