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

7.182K

Step-by-step 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;

`(V1)/(T1)=(V2)/(T2)`

To calculate, V2 we rearrange the formula;

`V2=(V1T2)/(T1)`

`V2=((5L)(395K))/(275)`

`V2=7.182K`

Therefore, the ending volume will be 7.182K
