Question

1. it rains and puddles form on the ground. the sun comes out and the puddles quickly disappear. explain what is happening to the water molecules in the puddle

Explanation:

When it rains, water accumulates as puddles (liquid state). When the sun comes out, heat energy from the sun is absorbed by the water in the puddle. This energy increases the kinetic energy of water molecules. As a result, liquid water undergoes evaporation (a type of vaporization), where liquid water molecules gain enough energy to break free from the liquid - liquid intermolecular forces and transform into water vapor (gaseous state), which then disperses into the air, causing the puddle to disappear.

Answer:

When it rains, water forms puddles (liquid water). When the sun shines, the water in the puddle absorbs heat, increasing the kinetic energy of water molecules. The liquid water molecules then undergo evaporation (vaporization), transforming from the liquid state to the gaseous state (water vapor) and dispersing into the air, making the puddle disappear.
