# The Minimum Volume of Container for Water Evaporation

## What is the minimum volume of a perfectly insulated and sealed container for a gallon of water at 25°C to evaporate completely?

Determine the dimensions in feet if the container is a cube.

## Minimum Volume of Container

The minimum volume of a perfectly insulated and sealed container for a gallon of water at 25°C to evaporate completely is approximately 0.00378541 m³. The dimensions of a cube container with this volume would be approximately 0.391 x 0.391 x 0.391 feet.

To determine the minimum volume of a container in which a gallon of water at 25°C will evaporate completely, we need to consider the saturation vapor density of water at 25°C. From the information provided, we can determine that the saturation vapor density of water at 25°C is 17.2 g/m³. We can convert the volume of a gallon of water (3.78541 liters) to cubic meters, which gives us a volume of approximately 0.00378541 m³. So the minimum volume of the container should be at least 0.00378541 m³ to allow a gallon of water at 25°C to evaporate completely.

To determine the dimensions in feet for a cube container, we can use the fact that 1 meter is approximately equal to 3.281 feet. Hence, the dimensions of the cube container would be approximately 0.391 x 0.391 x 0.391 feet.
