When does the water evaporation happens?
Evaporation of water occur when the energy of water molecules from the surface is sufficiently high and the molecules can escape in the atmosphere.
What is necessary for evaporation to occur?
For evaporation to occur, there must be heat energy available to increase the kinetic energy of the liquid molecules so they can escape into the air as vapor. Additionally, there should be an open space for the vapor to escape into the atmosphere.
Are necessary for evaporation to occur?
Three main factors are necessary for evaporation to occur: heat energy, a source of water, and an open space for the water molecules to escape into the air. Heat energy provides the necessary kinetic energy for water molecules to break free from the liquid. Without these factors, evaporation cannot take place.
What provides the energy needed for evaporation to occur naturally in the water cycle?
The kinetic energy of the molecules is the source.
Why evaporation happens at the surface?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
Why does water evaporate from your cup?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; but a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase.
Why does the water evaporates?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
How is the water evaporates?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
A fog forms over a lake. What two changes of state must occur to produce the fog Do the water molecules absorb or release energy during these changes of state?
First, water must evaporate from the lake. The water molecules absorb energy during evaporation. The water vapour in the air must condense to form the tiny water droplets that make up the fog. During condensation the water molecules release energy.
How does evaporation occur?
Evaporation is a spontaneous phenomenon. The molecules in the liquid possess kinetic energy. All the molecules donot possess the same kinetic energy. The molecules with higher kinetic energy are on the surface of liquids. They can readily overcome the intermolecular attractions and escape into the atmosphere. This phenomenon is known as evaporation. As the molecules with higher kinetic energy keep on escaping the whole kinetic energy of the liquid is lowered. Since energy is directly proportional to temperature. Thus evaporation causes cooling effect.
When water evaporates it?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere forming a gas. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
What causes evaporation of Earths waters to occur?
The cause of evaporation is the continuous movement of molecules at the surface of a liquid; gaining more energy they can escape in the air. Temperature favors this process.
