Does evaporation require heating?
Evaporation does not necessarily require heating, as it is a process driven by the molecules of a substance gaining enough energy to break free and become a gas. Heating can increase the rate of evaporation by providing more energy to the molecules.
Does transpiration require the plant to use any energy?
Yes, transpiration does not require the plant to use direct energy. The process is primarily driven by passive forces such as the evaporation of water from the plant's stomata and the cohesion of water molecules in the xylem.
Why does evaporation require that heat energy be added to a substance?
Evaporation requires heat energy to be added because it provides the molecules in a substance with enough kinetic energy to overcome the attractive forces holding them together. As molecules gain energy, they move faster and escape the liquid phase, transitioning into the gas phase. This process leads to evaporation.
Does evaporation release energy?
When vapours condense energy is released (the latent heat). Boilers designed for central heating can be made to give up this heat rather than throw it out with the flue gases as older units do.
Is evaporation the same as boiling?
No, evaporation occurs at the surface of a liquid at any temperature, while boiling specifically refers to the rapid vaporization of a liquid when it reaches its boiling point throughout the liquid. Evaporation is a slower process that happens at any temperature, while boiling is a faster process that occurs at a specific temperature.
Is energy released or required for evaporation?
require.

What are the types of phases change that require energy?
The types of phase changes that require energy are melting (solid to liquid), sublimation (solid to gas), and evaporation (liquid to gas). These phase changes require energy input to break the intermolecular forces holding the particles together in a particular phase.
Is evaporation of water release of energy?
Evaporation is an endothermic process, absorb energy.

What energy source causes evaporation?
Solar energy is the main energy source that causes evaporation. The heat from the sun provides the energy needed to convert water from liquid to gas, leading to evaporation.
Is evaporation affected by solar energy?
Yes, in fact solar energy is the cause of evaporation from the oceans
How is the rate of evaporation related to intermolecular forces?
The rate of evaporation is inversely related to the strength of intermolecular forces. Stronger intermolecular forces require more energy to break, resulting in a slower rate of evaporation. Weaker intermolecular forces allow molecules to escape more easily, leading to a faster rate of evaporation.
Is evaporation the same as boiling?
No, evaporation occurs at the surface of a liquid at any temperature, while boiling specifically refers to the rapid vaporization of a liquid when it reaches its boiling point throughout the liquid. Evaporation is a slower process that happens at any temperature, while boiling is a faster process that occurs at a specific temperature.
What is the source of energy for evaporation?
Kinetic energy.
