Question

the temperature of a balloon rises from 275 degrees k to 395 degrees k, what would the ending volume be if it started at 5 L

Answer 1

Answer:

7.182K

Explanation:

From the question we are given;

• Initial temperature, T1 = 275 K
• Final temperature, T2 = 395 K
• Initial volume, V1 = 5 L

We are required to calculate the final volume, V2

• Charles's law is the law that relates the volume of a gas and its temperature.
• It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
• Therefore;

$\frac{V1}{T1}=\frac{V2}{T2}$

To calculate, V2 we rearrange the formula;

$V2=\frac{V1T2}{T1}$

$V2=\frac{(5L)(395K)}{275}$

$V2=7.182K$

Therefore, the ending volume will be 7.182K
