Concept explainers
Interpretation: The volume of the gas at 130 oC needs to be determined if it is initially 980 mL at 27 oC temperature.
Concept Introduction:
The Charles’s law states that at constant pressure, the volume of the gas is directly proportional to its temperature. It is mathematically represented as follows:
Here, T1 is initial temperature, V1 is initial volume, T2 is final temperature and V2 is final volume.
Answer to Problem 4E
1316.3 mL
Explanation of Solution
The initial volume and temperature of the gas is 980 mL and 27 oC respectively. First convert the temperature from oC to K as follows:
Thus,
Now, the final temperature is given 130 oC which can be converted into K as follows:
Thus, final volume can be calculated from Charles’s law as follows:
Putting the values,
On rearranging,
Thus, the volume of the gas becomes 1316.3 mL at 130 oC.
