What is the latent heat of vaporization of water in kilo calorie per kg?
The latent heat of vaporization of water is approximately 2,260kJ/kg. 1 calorie = 4.186 J.
What is the latent heat of vaporization for water in J kg?
For the water substance at 1 atm and 100 °C (the boiling point of water at 1 atm), the latent heat of vaporization is 2.25 ÷ 106 J kg21.
What is the latent heat of vaporization of water in Cal and in joules?
The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.
How do you calculate the latent heat of vaporization of water?
Latent heat calculation The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .
What is the latent heat of vaporization of water in kcal?
For example, the latent heat of vaporization of water is 540 cal/g and the latent heat of freezing of water is 80 cal/g.
What is the specific heat of water in kcal kg?
Remarks
| Sea water | ||
|---|---|---|
| Density | 1.027 kg/l | At 0°C and salinity of 3.5%. |
| Specific heat | 0.94 kcal/kg°C | At 0°C |
| 0.93 kcal/kg°C | At 20°C | |
| Latent heat of fusion | 77-80 kcal/kg | Approximate values at salinities of up to 3.5%. Indeterminate owing to presence of salts. |
What is meant by specific latent heat of vaporization of water is 2.26mj kg?
Solution : This means that when one kg of water at its boiling point temperature changes into steam, 226 kj of heat is absorbed.
What is the latent heat of vaporization of steam?
The latent heat of vaporization of steam is 540 calories per gram, absorbed during vaporization or given up during condensation.
What is meant by saying that the latent heat of vaporization of water is 22.5 * 10/5 J kg?
Latent heat of vaporization of water in 22.5 X 105 Joules / kg means the heat require to vaporise 1kg of water is 22.5X 105 Joules / kg .
What does specific latent heat of vaporization of water 540 Cal g mean?
When 1 g of water at a pressure of one atmosphere and at a temperature of 100 °C is converted into 1 g of steam, heat absorbed by the water is 540 cal.
What does it mean that latent heat of vaporization of water is 22.5 10 5j kg?
What is meant by specific latent heat of vaporization of water is 2.26 MJ?
Answer: The specific latent heat of a substance is the amount of energy required to change the state of one kilo of the substance without change in its temperature. The latent heat of vaporization or evaporation is the heat given to some mass to convert it from the liquid to the vapor phase.
How many calories of latent heat does?
The latent heat of condensation will release 600 calories per gram of liquid water. – Sublimation is the process of changing vapor to a solid or from a solid to vapor (although the change from vapor to solid is sometimes called deposition). High ice clouds and dry ice are examples of sublimation.
What is the value of heat of vaporization of water?
around 540 cal/g
Heat of vaporization of water That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Water’s heat of vaporization is around 540 cal/g at 100 °C, water’s boiling point.
What is the latent heat of vaporization of ice?
Latent heat is the heat required to change the unit mass of substance. The latent heat of ice is 336kJkg−1 .
