No energy at all. Hydrogen (H2) is a stable gaseous compound.
ionization energy
The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.
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
When any substance goes from solid to liquid to gas, the kinetic energy of the molecules increases.Molecules in the gaseous state have the most kinetic energy.Molecules in the solid state have the least kinetic energy.
Gaseous state.
Gaseous State
water in a gaseous state
-- the gaseous state -- the state of heat exhaustion -- Texas

Evaporation is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state.
Water is made of water molecules whatever state it is in. In the gas phase the molecules are far apart and moving rapidly.
