Question

A boy blows up a balloon and knots the end. He leaves it on the kitchen counter. His little sister finds it and takes it outside in the sunshine.

According to Charles's law, which of the answer choices best predicts what will happen to the balloon?

Its pressure will increase.
Its temperature will decrease.
Its volume will increase.
Its volume will decrease.

Answer 1

I pretty sure it’s (C) it’s volume will increase.

I hope this helped!

Answer 2

Answer : The correct option is, Its volume will increase.

Explanation :

According to the Charles' Law, the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$

That means the volume of gas is directly depends on the temperature of the gas.

As, the temperature of the gas increase, the volume of gas will also increases and vice-versa.

As per question, when a boy blows up a balloon and knots the end then he leaves it on the kitchen counter. When his little sister finds it and takes it outside in the sunshine then the volume of the balloon increases due to increase in the temperature.

Hence, the correct option is, Its volume will increase.
