They go from moving around slightly, to moving around quickly and separating from one another. This is causes by evaporation.
What else can I help you with?
How does the motion of the molecules change during evaporation?
They go from moving around slightly, to moving around quickly and separating from one another. This is causes by evaporation.
What is the chemical change in evaporation?
There isn't one. Evaporation is a physical change.
How does the motion of the molecules change during melting?
The motion of molecules is accelerated.
Why does water change from a liquid to a gas in evaporation?
Evaporation is caused by the continuous Brownian movement of water molecules; several molecules gain sufficient energy to escape in the atmosphere.
What type of phase change is evaporation?
Evaporation is a phase change from liquid to gas, where molecules at the surface of a liquid gain enough energy to escape into the gas phase.
What properties of water allow it to exist as a liquid in oceans and rivers?
Its molecules are in constant motion, allowing for evaporation and condensation.
The change from a liquid to a gaseous state?
The change from a liquid to a gaseous state is called evaporation. During evaporation, molecules gain enough energy to escape from the liquid phase and become gas molecules. This process occurs at the surface of the liquid.
Is evaporation of water from a lake a chemical reaction?
No, evaporation of water from a lake is a physical process, not a chemical reaction. It involves the transformation of water from a liquid to a gas without any change in the chemical composition of water molecules.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
The process is called evaporation. Molecules at the surface of a liquid gain energy from the surroundings, typically heat, causing them to overcome the intermolecular forces holding them together. Once they have enough energy, these molecules transition to the gaseous state and escape from the liquid surface.
What is evaporation do when its outside?
Evaporation- The process which molecules at the surface of a liquid, such as water, absorb enough energy to change to a gaseous state, such as water vapor.
Does heating water increasing the rate of evaporation?
Yes, heating water does increase the rate of evaporation. When water is heated, the molecules gain energy and move faster, which allows more molecules to escape from the surface of the water and evaporate.
Do molecules stay the same during physical change?
Yes, during a physical change, molecules remain the same. The arrangement and motion of molecules may change, but the actual atoms that make up the molecules do not change.
