What is meant by the statement that the specific latent heat of steam is 2260000jkg
Good
The specific latent heat of steam refers to the amount of energy required to change the state of 1 kilogram of water from a liquid to a gas, or vice versa, at a constant temperature and pressure. In this case, the specific latent heat of steam is stated to be 2260000 joules per kilogram (J/kg).
To see how this value is used, let's consider an example. Suppose you have 1 kilogram of water at 100 degrees Celsius (C), which is its boiling point. If you want to convert this water to steam, you would need to provide energy equal to the specific latent heat of steam, which is 2260000 J/kg.
So, to calculate the total amount of energy required, you can multiply the specific latent heat by the mass of the water. In this case, the mass is 1 kilogram:
Total energy = Specific latent heat * Mass
Total energy = 2260000 J/kg * 1 kg
Total energy = 2260000 J
Therefore, it would take 2260000 joules of energy to convert 1 kilogram of water at its boiling point into steam.
