Question

A weather balloon contains 135 liters at 21.0 oC. What is it’s volume when the temperature is -4 oC?

Answer 1

V₂ = 123.5 L

Step-by-step explanation:

Given data:

Initial volume = 135 L

Initial temperature = 21.0 °C

Final volume = ?

Final temperature = -4°C

Solution:

-4+273 = 269 k

21.0+273 = 294 k

V₁/T₁ = V₂/T₂

V₂ = V₁.T₂/ T₁

V₂ = 135 L . 269 K / 294 K

V₂ = 36315 L . K / 294 K

V₂ = 123.5 L
