Interpretation: The new volume of the balloon needs to be determined.
Concept Introduction:
The ideal gas equation is represented as follows:
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.
Answer to Problem 4RE
588 mL.
Explanation of Solution
Given Information:
The initial volume and temperature of the air in balloon is 600 mL and 27 oC respectively. The final temperature is 21 oC .
Calculation:
First convert the given temperature to K as follows:
Thus,
Thus,
Also,
Thus,
The ideal gas equation is as follows:
For constant pressure and number of moles:
On rearranging,
Putting the values,
Thus, the new volume of the air in balloon is 588 mL.
