The balloon might pop due to the increase in the volume of the gas.
Step-by-step explanation:
According to the given situation the balloon will explode in a hot day. This is because Boyles law shows that, when the temperature inside a gas particle increases, the "volume of the particle" also increases. This means the volume of the balloon will increase on an extremely hot day or even on a slightly warmer day. The increase in volume of the balloon causes it to explode.
Suppose the temperature was less, the volume of the gas particles would have decreased. This can also be explained with the help of Charles law where he explains the relation between temperature and volume.
Note: Charles law and Boyles law are called the gas laws.
