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

V₂ = 123.5 L

Explanation:

Given dа ta:

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
