how much kilogram does boiling water gives off
To determine how much kilogram (kg) of water vapor is given off when boiling water, we need to consider its change in state from liquid to gas (vapor).
First, we need to know the mass of the water that is being boiled. Let's assume we have 1 liter (L) of water, which is equal to 1 kilogram (kg). However, this can vary depending on the temperature and altitude.
The specific heat capacity of water is approximately 4.18 kilojoules per kilogram per degree Celsius (kJ/kg·°C). This means it takes 4.18 kilojoules of energy to raise the temperature of 1 kilogram of water by 1 degree Celsius.
Next, we need to consider the latent heat of vaporization (also known as enthalpy of vaporization) of water. The latent heat of vaporization is the amount of energy required to change 1 kilogram of a substance from liquid to gas at its boiling point, which for water is 100 degrees Celsius.
For water, the latent heat of vaporization is approximately 2260 kilojoules per kilogram (kJ/kg). This means that to convert 1 kilogram of water at 100 degrees Celsius into vapor, 2260 kilojoules of energy are needed.
Therefore, when boiling 1 kilogram of water at 100 degrees Celsius, approximately 2260 kilojoules of energy are required to fully vaporize it.
Keep in mind that these values are approximations and can vary slightly depending on factors such as pressure and impurities in the water.
