Question

If you can answer it with another sheet answering all that I would appreciate it.

Answer 1

1- volume of balloon = 0.46949 L
2- volume = 0.71399 L
3- V = 0.28510 L = 285.102 mL
4- V = 1.80537 L

Step-by-step explanation:
It's all about Charles' law

Charles' law: The volume of an ideal gas is directly proportional to the absolute temperature AT CONSTANT PRESSURE.

then, we conclude that:


`(V_(1) )/(T_(1) ) = (V_(2) )/(T_(2) )`

in which V1 : initial volume in Liters, T1: initial temperature in Kelvin, V2: final volume in Liters, T2: final temperature in Kelvin.

*Temperature in Kelvin = Temperature in Celsius + 273

in Q1:


`(0.5)/(22+273) =(V_(2) )/(4+273)`


`V_(2) = (0.5(4+273))/(22+273) = 0.46949 L`

in Q2:

`(0.4)/(293) = (V_(2))/(523)`


`V_(2) = (523 * 0.4 )/(293) = 0.71399 L`

in Q3:


`(0.25)/(292) = (V_(2))/(333)`


`V_(2) = (333*0.25)/(292) = 0.285102 L = 285.102mL`

in Q4:


`(2)/(298) = (V_2)/(269)`


`V_2 = (2*269)/(298) = 1.80537 L`
