What else can I help you with?
Is evaporation energy loss or gain?
Evaporation is considered an energy gain process because it requires energy input to break the bonds between liquid molecules to change them into vapor. This energy input comes from the surrounding environment, which leads to cooling of the remaining liquid.
What is high heat of evaporation?
High heat of evaporation refers to the amount of energy required to convert a liquid into a gas at its boiling point. Substances with a high heat of evaporation require more heat input to change their state, making them more resistant to vaporization. Water is a notable example of a substance with a high heat of evaporation.
Energy is what during evaporation?
Energy is absorbed from the surroundings during evaporation to break the intermolecular forces between liquid particles, allowing them to escape into the gas phase. This energy input is necessary to overcome the attractive forces holding the liquid molecules together and convert them into vapor.
When the hydrosphere receives energy from the Sun what does water do A.condenses. B.precipitates. C.evaporates. D. runs off?
The only process which requires the input of energy is evaporation.
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
Which process in the water cycle requires the direct input of energy?
Evaporation.
What is the change from liquid to a gas?
Evaporation, at a rate proportional to heat input and temperature specific to the fluid to a maximum set by the pressure.
Energy release is to condensation as energy input is to?
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
Is evaporation energy loss or gain?
Evaporation is considered an energy gain process because it requires energy input to break the bonds between liquid molecules to change them into vapor. This energy input comes from the surrounding environment, which leads to cooling of the remaining liquid.
Which is not a process the decreases the salinity of seawater?
Evaporation is a process that increases the salinity of seawater, not decreases it. Other processes that decrease the salinity of seawater include precipitation, melting of icebergs, and the input of freshwater from rivers.
What is high heat of evaporation?
High heat of evaporation refers to the amount of energy required to convert a liquid into a gas at its boiling point. Substances with a high heat of evaporation require more heat input to change their state, making them more resistant to vaporization. Water is a notable example of a substance with a high heat 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.
With the input of solar energy water changes from a liquid to a gas during the process of?
evaporation. This happens when sunlight heats up the water molecules, causing them to gain enough energy to escape into the air as water vapor.
Is the Sea of Cortez saltier because fresh water input is low and evaporation is high?
Yes, that is correct. The Sea of Cortez is a marginal sea with limited freshwater input from rivers, resulting in higher salinity levels. Additionally, the hot and arid climate in the region leads to high rates of evaporation, further concentrating the salt content in the water.
What do you need for evaporation to take place?
Evaporation occurs when a liquid changes into a gas due to the input of heat energy. It requires adequate surface area for the liquid to be exposed to the air, as well as a lower atmospheric pressure compared to the liquid. Additionally, evaporation is influenced by factors such as temperature, humidity, and air movement.
Is a puddle evaporating an exothermic reaction?
Evaporation of a puddle is a physical process, not a chemical reaction. It is an endothermic process because it requires energy input to overcome the intermolecular forces holding the liquid molecules together.
Energy is what during evaporation?
Energy is absorbed from the surroundings during evaporation to break the intermolecular forces between liquid particles, allowing them to escape into the gas phase. This energy input is necessary to overcome the attractive forces holding the liquid molecules together and convert them into vapor.
