To vaporize water at 100 degrees Celsius into steam at the same temperature, water requires a specific amount of thermal energy known as the **enthalpy of vaporization** or **latent heat of vaporization**.

For water, the latent heat of vaporization is approximately **2260 joules per gram (J/g)** at 100 degrees Celsius.

Thus, a gram of water at 100 degrees Celsius must gain about **2260 joules** of thermal energy to vaporize into a gram of steam at 100 degrees Celsius.
