During evaporation, a liquid turns into a gas or vapor by gaining energy from its surroundings. The molecules of the liquid gain enough energy to overcome the attraction forces holding them together in the liquid state. As they gain energy, the molecules move more rapidly and eventually break free into the surrounding environment as a gas.
What else can I help you with?
Is heat taken away or added in evaporation?
Heat is taken away during evaporation. As the liquid absorbs heat from its surroundings and gains energy, some of the molecules at the surface of the liquid gain enough energy to overcome the intermolecular forces holding them together, and they escape into the gas phase. This process removes heat from the remaining liquid, causing it to cool down.
How do you know whether osmosis has taken place?
Osmosis has taken place when there is a net movement of solvent molecules from an area of higher concentration to an area of lower concentration across a semi-permeable membrane. This can be observed by changes in the volume or concentration of the solutions on either side of the membrane.
What are four things that indicate that a chemical change may have taken place?
Change in color: If the substance changes color during a reaction, it may indicate a chemical change. Formation of gas: Production of gas bubbles, fizzing, or bubbling is a sign of a chemical change. Temperature change: Significant heat or cooling effects can indicate a chemical reaction is occurring. Formation of a precipitate: When a solid substance forms in a solution, it suggests a chemical change has taken place.
Do you think a chemical reaction has taken place Can you explain your reasoning behind your conclusion?
Yes, a chemical reaction has likely taken place if there is a change in the chemical composition of the substances involved. This can be observed through the formation of new substances, changes in color, temperature, or the release of gas. These are all indicators that a chemical reaction has occurred.
Can you list three kinds of changes that indicate a chemical reaction has taken place?
Some signs that a chemical change has taken place is that a gas can be produced, the temperature can change, and a substance disappears. Other signs are that a solid is formed, the color changes, and a new odor is produced.

Is heat released to the environment or taken up from the environment during evaporation?
Heat comes from one source, the sun.
Why is cooling always caused during evaporation?
Cooling occurs during evaporation because the process requires energy to convert liquid water into water vapor. This energy is taken from the surrounding environment, leading to a decrease in temperature.
