What Happens When Very Cold Liquid is Poured Over a Balloon?

What happens when very cold liquid is poured over a balloon?

A) The balloon gets smaller. B) The balloon bursts. C) The balloon rises. D) The balloon expands.

Answer:

The balloon gets smaller.

When very cold liquid is poured over a balloon filled with air, the balloon will shrink or get smaller. This happens because the cold temperature causes the air particles inside the balloon to slow down, reducing their average kinetic energy. As a result, the air pressure inside the balloon decreases, causing the balloon to deflate.

The decrease in temperature lowers the average kinetic energy of the gas particles inside a sealed balloon, causing the balloon to decrease in volume or get smaller. This physical change occurs without any transfer of energy by heat to or from the balloon.

This phenomenon is explained by the principles of thermal physics. When a sealed balloon is exposed to a significant decrease in temperature, such as when cold liquid is poured over it, the average kinetic energy of gas particles inside the balloon decreases. As a result, the overall volume of the balloon decreases, leading to the balloon getting smaller.

Therefore, the correct answer to the question "What happens when very cold liquid is poured over a balloon?" is that the balloon gets smaller.
