How much water is vaporized

How much energy is available? Natural resources for power generation have traditionally been waterfalls or use of oil, coal, or nuclear power to generate electricity.

Research is being carried out to look for other renewable sources to run the generators. Geothermal sites such as the geyser pictured above are being considered because of the steam they produce. Capabilities can be estimated by knowing how much steam is released in a given time at a particular site. Energy is absorbed in the process of converting a liquid at its boiling point into a gas. As with the melting of a solid, the temperature of a boiling liquid remains constant and the input of energy goes into changing the state.

The molar heat of vaporization of a substance is the heat absorbed by one mole of that substance as it is converted from a liquid to a gas. As a gas condenses to a liquid, heat is released. The molar heat of condensation of a substance is the heat released by one mole of that substance as it is converted from a gas to a liquid.

Make Shortcut to Home Screen? Online Water Heat of Vaporization Calculator The calculator below can be used to calculate the liquid water heat of vaporization at vapor pressure at given temperatures. What is the heat in joules required to convert 25 grams of water into steam? What is the heat in calories?

Note: You won't be expected to know enthalpy or heat values; they will be given in a problem or can be looked up in a table. You can solve this problem using either joules or calories for heat. The amount of heat required to change 25 grams of water into steam is joules or calories. A related example illustrates how to calculate the energy when water changes from solid ice into steam.
