== == According to Charles's Law, "At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases."

Therefore, if the temperature of the gas is decreased, the volume of the gas will decrease proportionally, and the balloon will contract.
