Intermolecular forces, i.e. hydrogen-bonds, have to be broken down in order for water molecules to escape to the vapor phase. Energy is needed in the process to set water molecules free.

Why do you need heat to boil water?
Boiling water requires heat to increase the temperature of the water molecules, causing them to gain enough energy to overcome the intermolecular forces holding them together in the liquid state. This results in the water reaching its boiling point and transforming into vapor.
What is energy and why do you need it?
Energy is the ability to do work or cause change. You need energy to fuel your body's functions, such as metabolism, movement, and brain function. Energy is essential for sustaining life and carrying out daily activities.
Is this statement true or false Water vapor does not need a solid object on which to condense.?
True. Water vapor can condense directly into liquid water without needing a solid object as a surface for condensation to occur. The process of condensation can happen in the air when water vapor cools and reaches saturation point.
Does condensation need heat energy?
Yes, condensation requires the removal of heat energy, as it is the process by which a gas changes to a liquid by losing heat. When water vapor in the air cools and loses energy, it condenses into liquid water droplets.
Why does evaporation need the sun in order for it to occur?
Evaporation requires heat energy to overcome the intermolecular forces holding water molecules together. The sun provides this heat energy by warming the surface of water bodies, increasing the kinetic energy of water molecules and allowing them to escape as vapor. Without the sun's energy, the water would not have enough thermal energy to evaporate.
What does water vapor need in order to change states from a gas to a liquid?
Water vapor needs to lose energy in the form of heat in order to change states from a gas to a liquid, a process known as condensation. This energy loss causes the water vapor molecules to slow down and come together to form liquid water droplets.
What factors are needed for cloud formation?
You need water vapor, kinetic energy, and energy surrounding inside the atmosphere.

Why does water vapor need solid particles in the atmosphere to form clouds?
Particles are needed because then the water vapor can condense on them
How do you turn water into water vapor?
You just need to cool it down.
How do you turn water vapor into water?
You just need to cool it down.
Explain in terms of particles what happens when steam condenses on a cold mirror?
When steam (water vapor) comes in contact with a cold mirror, it loses heat energy to the mirror. As a result, the water vapor particles slow down and come closer together, transitioning into liquid water droplets. This process is called condensation, where the gas phase (water vapor) turns into the liquid phase (water droplets) due to the loss of thermal energy.
What caused the water to change from liquid water to water vapor?
Either evaporation or the water was boiled. But, in general explanation, the molecule of water need certain energy to break its inter molecular force to cause it being vaporized. So if the quantity energy needed is fulfilled, the state is changing from liquid to gas.

How do you change water vapour into water?
Water vapor can be changed into water through a process called condensation. By exposing the water vapor to cooler temperatures, it loses energy and transforms back into liquid water. This can be seen in everyday examples such as dew forming on grass in the morning or steam turning back into water when it cools down.
Why is Air masses important?
It is important because of all the water vapor that we need.
What steps must take place in order for ocean water to become rain?
Evaporation: Heat from the sun causes water from the ocean to evaporate into the atmosphere. Condensation: The water vapor in the atmosphere cools and condenses into clouds. Precipitation: When the clouds become saturated with water droplets, precipitation occurs in the form of rain.
