Answer:
0.68 liters
Step-by-step explanation:
We can use Charles Law to solve this:
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
Where
V_1 is initial volume of balloon
V_2 ballon's final volume [what we ought to find]
T_1 Balloon's initial Temperature
T_2 Fridge's initial temprature
* Remember, we need to make Celcius to Kelvin by adding 273
So,
V_1 = 0.75
V_2 = what we need to find
T_1 = 30 + 273 = 303
T_2 = 0 + 273 = 273
Plugging, and solving, we get:
[tex]\frac{0.75}{303}=\frac{V_2}{273}\\0.75*273=303V_2\\204.75=303V_2\\V_2=\frac{204.75}{303}\\V_2=0.68[/tex]
Final Volume of Balloon = 0.68 Liters
