Interpretation:
The new volume of the balloon as it expands from an initial volume of 1.35 L and temperature 22 oC to a final temperature of 32 oC needs to be calculated.
Concept introduction:
The relation between volume (V) and temperature (T) of a gas under constant pressure and amount of the gas is represented through Charles Law.
As per Charles law, volume is directly related to temperature:

Answer to Problem 9STP
(C) 1.4 L
Explanation of Solution
Given:
Initial volume of balloon, V1 = 1.35 L
Initial temperature, T1 = 22°C
Final temperature, T2 = 32°C
Calculation:
Based on equation (1):
The volume of balloon at a final temperature of 32 oC is 1.4 L.
