Question

A filled balloon has a volume of 5.6 L at 35 ˚C and it is placed into liquid nitrogen at a temperature of -78 ˚C. What is the new volume of the balloon?

Answer 1

3.54 L

Step-by-step explanation:

To find the new volume, we'll use this formula:
`(V_1)/(T_1) = (V_2)/(T_2)`

V₁ = Liters (5.6)

T₁ = Volume in kelvin (273 + 35 = 308)

V₂ = New liters (?)

T₂ = New temperature (273 - 78 = 195)

`(5.6)/(308) = (V_2)/(195)`

First, cross multiply

1092 = V₂308

Divide both sides by 308

1092/308 = V₂308/308

V₂ = 3.54
