What else can I help you with?
Which process in the water cycle requires the direct input of energy?
Evaporation.
What is evaporation an exothermic or endothermic process?
Evaporation is an endothermic process because it requires energy in the form of heat to break the intermolecular forces holding the liquid molecules together. This energy is absorbed from the surroundings, leading to a decrease in temperature.
What happens to the temperature of the surrounding air when evaporation occurs?
When evaporation occurs, the temperature of the surrounding air decreases because the process of evaporation requires energy, which is taken from the surrounding environment, causing a cooling effect.
Evaporation of perspiration is an endothermic or exothermic change Why?
Evaporation of perspiration is an endothermic process because it requires energy from the surroundings to break the intermolecular forces that hold the water molecules together. As the sweat evaporates, it takes energy from the skin, resulting in a cooling effect.
Is alcohol evaporation endothermic or exothermic?
Always endothermic. Liquids absorb heat from the surroundings through evaporation, and keeps continuing this to regain lost energy. This produces a cooling effect in the surroundings.
Evaporton is a phase change form?
Evaporation is a phase change process in which a liquid turns into a gas. This occurs when molecules at the surface of the liquid gain enough energy to break free and enter the gas phase. Evaporation is a cooling process because it requires energy, which is typically taken from the surrounding environment.
Is evaporation a gasliquidorsolid?
Evaporation is neither gas liquid or solid. Evaporation is a process. It is the process of turning a liquid into a gas
Is an example of an endothermic process Condensation Evaporating Burning or Freezing?
An example of an endothermic process is evaporating. Evaporation requires an input of energy to convert liquid water into water vapor, so it is an endothermic process.
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.
What is evaporation of alcohol it is exothermic or endothermic?
Evaporation of alcohol is an endothermic process because it requires energy to break the intermolecular forces holding the alcohol molecules together. This energy is absorbed from the surroundings, resulting in a cooling effect.
Why is evaporation of water from your skin a cooling process?
Evaporation of water from the skin is a cooling process because it requires heat energy from the skin to convert liquid water into water vapor. This heat energy is drawn from the skin's surface, resulting in a cooling sensation.
Evaporation is a cooling process because?
evaporation is a cooling process because it requires energy in the form of heat from the surroundings to change liquid water into water vapor. This energy is absorbed from the surroundings, resulting in a decrease in the temperature of the surroundings, leading to a cooling effect.
