Where Did the Water in the Puddle Go

Six friends were walking to the park on a sunny day. They noticed a big puddle

on their way to the park. When they came back two hours later, the puddle was

gone. They each had different ideas about where the water in the puddle went.

This is what they said:

Bandari: The water went right up to the clouds.

Regina: The sun dried the water up and it no longer exists.

Dylan: All of the water soaked into the ground.

Axel: Much of the water is in the air around us.

The water went into a stream, river, pond, lake, or ocean.

Clinti: The water changed into fog.

Axel: Much of the water is in the air around us.

Explanation:

When a puddle of water forms on the ground, it indicates that much of the ground around it is saturated with water and as such, the water would not readily soak into the ground. Also, since the puddle was found in a park, it is not likely that the water has gone into a stream, river, pond, lake, or ocean.

Since, the day was a sunny, it means that the heat from the sun has caused the evaporation of the water molecules. However, the water vapor molecules do not just immediately rise up to the atmosphere to form clouds nor do they cease to exist, rather it is dispersed in the air around the surroundings and beyond. Formation of clouds by water vapor takes days to happen.

Also, the water has not changed to fog either as they form usually at cooler temperatures.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
