Evaporation is the action of molecules escaping the bonds of neighboring molecules. At temperatures above absolute zero, molecules have energy that is expressed in motion. With enough of this motion, water molecules at the surface of water can break the bonds they have with their neighbors. They can escape the liquid and move into the air. When molecules leave the water, there is now less water, which is what we call evaporation.
So if you have a dish that exposes more molecules to an area where they can escape the other molecules (in other words, the surface), obviously more will escape. A wide, flat, shallow container exposes many more water molecules to the surface than the same amount of water in a tall, narrow container.
The time it takes for a cup of boiling water to evaporate on the stove depends on factors like the heat setting, pan size, and humidity. On average, it can take around 10-20 minutes for a cup of boiling water to completely evaporate in a small to medium-sized pan.
Water in a preheated pan may not evaporate immediately because the water needs to reach its boiling point before it evaporates. Once the pan reaches a high enough temperature to boil the water, the water will start to evaporate into steam.
The sand is most likely to heat up faster, particularly if it is dark. The water will have some evaporation, which will keep it cooler. It can also vary by how it is subjected to the sun's heat, like a flat pan or a colored cup, or clear vessel.
Less heat will escape with the lid on. As the pressure inside the pan increases, the liquid boils faster - so both aspects combined makes the water to boil faster and save energy. Without a lid, the water won't boil as fast or as quickly, and more energy will be used.
- increase the temperature- decrease the pressure
If you place 1 cup of water in a mug and a loaf pan in a sunny window, the water in the mug will likely evaporate faster due to the larger surface area exposed to the sunlight and air compared to the water in the loaf pan. This is because the rate of evaporation is influenced by surface area, temperature, and air circulation.

To quickly evaporate water while cooking, increase the heat and surface area of the liquid by using a wide pan or pot. This will help the water evaporate faster, leaving behind the desired flavors and textures in your dish.

Water will evaporate faster with alid on the pan, this is simple rule of kinetic energy
you put the water in a pan and heat it till the water evapourates

When water is in a pan over a flame, the heat from the flame is transferred to the water through conduction. As the water molecules gain energy, they move faster, which causes the overall temperature of the water to increase. This process continues until the water reaches its boiling point and starts to evaporate.

When a pan of saltwater is boiled dry, the water evaporates, leaving behind the salt crystals in the pan. The salt does not evaporate with the water and remains in the pan as a solid residue.
Increasing the temperature of the water can make it evaporate more quickly. Using a lid to cover the pan can also help trap heat and increase the rate of evaporation. Additionally, increasing air circulation around the pan can help speed up the evaporation process.
