<h3>Answer:</h3>
7.182K
<h3>Explanation:</h3>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;
To calculate, V2 we rearrange the formula;
Therefore, the ending volume will be 7.182K
Given information :
G = 173.3 KJ
H = 180.7 KJ
T = 303.0 K
S = unknown (?)
By using the given formula : G = H - TS , we can calculate the value of 'S'
On rearranging the formula we get : S =
Plug in the value of G , H and T in the above formula :
S =
S = 0.02442
