Variable is any factor, trait, or condition that can exist in differing amounts or type. experiments usually have three kids of variables: independent, <span>dependent, and controlled. independent variable is the one that gets changed by the scientist. i hope this helps alot</span>

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
goldfiish [28.3K]

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.
