No energy at all. Hydrogen (H2) is a stable gaseous compound.
The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called evaporation. This occurs when the kinetic energy of the molecules overcomes the intermolecular forces holding them in the liquid state.
ionization enthalpy means the energy required to remove an electron from isolated gaseous atom in its ground state . the isolated gaseous state is the state in which no other force of attraction acting on an atom form other atom . so that, we get the exact energy required to romove or add an electron to an atom. and here ground state is used to say that electron are stable and are not exited .. so , the ionization enthalpy is the energy required to remove an electron from gaseous atom which is free from other atom in that state in which electrons are stable. by shashank
ionization energy
The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.
Condensation is the process in which a substance changes from a gaseous state to a liquid state. This occurs when the gas loses energy (usually in the form of heat) and becomes more tightly packed together, forming liquid droplets.
When thermal energy is released, water turns from a liquid state to a gaseous state, becoming water vapor or steam.
Gaseous State
water in a gaseous state
When steam condenses, it gives off thermal energy because the molecules are transitioning from a higher-energy state (gaseous phase) to a lower-energy state (liquid phase). This excess energy is released into the surrounding environment as heat.
When water molecules evaporate, they gain energy from their surroundings to break free from the liquid state and enter the gaseous state. This absorption of energy from the environment causes a cooling effect in the surrounding area.
thermol
Water is made of water molecules whatever state it is in. In the gas phase the molecules are far apart and moving rapidly.
