Question

if you place a balloon filled with air into a fridge, what will happen?
select the correct answer below:
the temperature will increase and the volume will increase.
the temperature will increase and the volume will decrease.
the temperature will decrease and the volume will decrease.
the temperature will decrease and the volume will increase.

Explanation:

Step1: Analyze temperature change

When the balloon is placed in the fridge, heat is transferred from the air inside the balloon to the cooler environment of the fridge. According to the zeroth law of thermodynamics, heat flows from a higher - temperature object to a lower - temperature object. So, the temperature of the air inside the balloon decreases.

Step2: Apply Charles's Law

Charles's Law is given by the formula \(V = kT\) (where \(V\) is volume, \(T\) is temperature in Kelvin, and \(k\) is a constant for a given amount of gas at constant pressure). Assuming the pressure inside the balloon remains approximately constant (the elastic force of the balloon and the external atmospheric pressure do not change drastically in this simple case), when \(T\) (temperature) decreases (since \(T_{final}

Answer:

The temperature will decrease and the volume will decrease.
