The latent heat of vaporization
The term for the amount of energy required for a liquid at its boiling point to become a gas is called the latent heat of vaporization. This energy is needed to overcome the intermolecular forces holding the liquid molecules together and allow them to escape as a gas.
When energy is added to a liquid causing it to change into a gas, it is called vaporization or evaporation. This process involves the liquid molecules gaining enough energy to break free from the attractions holding them together in the liquid phase and transition into the gaseous phase.
The process of changing gas to liquid is called condensation. This occurs when gas molecules lose energy and come together to form a liquid.
When a liquid gains energy and changes into a gas, it is called vaporization or evaporation. This process involves the molecules of the liquid gaining enough energy to overcome the intermolecular forces holding them together as a liquid.
The latent heat of vaporization indicates the amount of heat energy required to change one unit of mass of a substance from liquid to gas at constant temperature. It is a measure of the strength of the intermolecular forces holding the liquid together.
The energy needed to go from a liquid to a gas is referred to as heat of vaporization.
Yes, energy is required for a liquid to change into a gas. This process is known as vaporization or boiling and it requires the liquid to absorb heat energy to overcome intermolecular forces and become a gas.

it depends
The process from a liquid to a gas is called evaporation, where the liquid absorbs heat energy and changes into a gas. On the other hand, the process from a gas to a liquid is called condensation, where the gas loses heat energy and changes into a liquid. Both processes involve a change in temperature or pressure.
The energy required to go from liquid to gas is known as the heat of vaporization. It represents the amount of energy needed to convert one unit of a substance from liquid to gas at its boiling point. The heat of vaporization varies for different substances and is typically expressed in units of joules or calories per gram.
Condensation. A gas condenses into a liquid.
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
When energy is added to a liquid causing it to change into a gas, it is called vaporization or evaporation. This process involves the liquid molecules gaining enough energy to break free from the attractions holding them together in the liquid phase and transition into the gaseous phase.
The transition from a gas to liquid is called condensation
The process of changing gas to liquid is called condensation. This occurs when gas molecules lose energy and come together to form a liquid.
The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away. Any mass of liquid water will have a range of energies for the molecules, some will be low energy, others high energy with each collision between the molecules, they either gain or loose energy. If they gain enough energy, they can become energetic enough to escape the liquid as a gas. The higher the pressure, the more energy is required to become a gas. If the liquid water is in contact with some gas - air for example. The liquid will evaporate until the gas is saturated with water vapor. At that point the rate of water molecules dropping out of the gas back into the water (because they don't have enough energy to stay in the gas) is equal to the rate of water molecules escaping from the liquid to become gas. This point is also known as "equilibrium".
