Expansión y conducción – ¿Qué sigue?

The video explains how temperature affects the size of a balloon. In cold conditions, the gas inside the balloon contracts, causing the balloon to shrink. When the balloon is taken out and exposed to heat, the gas expands, and the balloon returns to its original size.

What happens to the gas inside a balloon when it is exposed to cold temperatures?

• The gas evaporates.

• The gas remains the same.

• The gas contracts.

• The gas expands.

Why does a balloon shrink when it is taken out into the cold?

• Because the gas inside evaporates.

• Because the gas inside contracts.

• Because the air pressure outside increases.

• Because the balloon material becomes brittle.

What causes the balloon to return to its original size after being taken back inside?

• The air pressure outside decreases.

• The balloon material stretches.

• The balloon is filled with more gas.

• The gas inside the balloon expands.

How does heating affect the gas inside a balloon?

• It causes the gas to solidify.

• It causes the gas to liquefy.

• It causes the gas to expand.

• It causes the gas to contract.

What is the primary reason for a balloon's size change when temperature changes?

• The material of the balloon changes.

• The weight of the balloon changes.

• The gas inside the balloon changes volume.

• The color of the balloon changes.
