Question

A balloon has a volume of 10,500 liters, and the temperature is 15°C. If the temperature were -25°C, what would the volume of the balloon be? 12,194 L 9,042 L

Answer 1

to say that the answer is 8823 is ridiculous.

Step-by-step explanation:

If you read the question he is only giving you two choices, 12,194 L and 9,042 L. The answer to your question is the second option, 9,042 L.

Answer 2

According to Charle's law; the volume of a fixed mass of a gas is directly proportional to the absolute temperature at constant pressure.
VT= a constant
V1/T1 = V2/T2
V1 = 10,500 liters, T1= 15+273 =288 K; V2= ?, T2 = -25 +273 = 242 K
10,500/288 = V2/242
V2 = (10,500 ×242)/288
= 8822,92 Liters
Therefore; the new volume of the balloon will be 8823 Liters
