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 work. It exists in all matter and is what makes everything move, grow, heat up, change phase, even light is energy. Energy can neither be created nor destroyed. The use and existence of energy is what is making everything happen around you. Take for instance an ice cube. The ice has both potential (stored) energy and kinetic energy. Heat from other energy sources is melting the ice which is then releasing its stored energy to form water. The water is also evaporating at some point to form vapor. All of the phase changes are transfers of energy from the air into the ice or water. The ice has low energy and as more energy is absorbed it melts and then vaporizes. Water vapor has higher energy than ice through this process (which is known as convection). If you continue to add heat (energy) to the vapor it will become steam which has so much energy, it has been used for more than two centuries to drive turbines. When the steam hits the blades of the turbine it causes them to turn, there-by transferring its energy to the turbine and the steam becomes "weaker" or lower energy.
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 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.
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 vapor into water?
You just need to cool it down.
How do you turn water into water vapor?
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 Vapour is removed from the kitchen by a ventilation system that is often installed over the stove which leads through the vents to the outside wall of the house, propelling the substance into the environment.
Why is Air masses important?
It is important because of all the water vapor that we need.
Is water heated from water vapour?
Water is typically heated from a liquid state, not from water vapor. Water vapor forms when liquid water is heated to its boiling point and evaporates into the air. To heat water using water vapor, one would need to first condense the vapor back into liquid water before further heating it.
