What is the latent heat of vaporization of water in J G?

What is the latent heat of vaporization of water in J G?

2260 J/g.
The latent heat of vaporization of water is 2260 J/g.

What is latent heat of vaporization of water in KG?

The latent heat of vaporization of water is approximately 2,260kJ/kg. 1 calorie = 4.186 J.

What is heat of vaporization Brainly?

Answer: heat absorbed when a liquid vaporizes specifically : the quantity of heat required at a specified temperature to convert unit mass of liquid into vapor.

When we say that latent heat of vaporization of 1 g of water is 2260 J What do we mean by this?

Q is the amount of heat needed to convert water in steam; m is the mass of the water. So: m=QL=226000J2260Jg=100g .

What is latent heat of vaporization value?

The enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas.

What is the latent heat of vaporization of water class 9?

Latent Heat of Vaporization (liquid to gas change): The latent heat of vaporization of water is 22.5×105 joules per kilogram (or 22.5×105 j/kg).

What is latent heat of vaporisation Class 9?

The term latent heat of vaporisation can be defined as the amount of heat needed for the conversion of 1kg of liquid at its boiling point to gas at same temperature.

How can you show that evaporation causes cooling?

When liquid changes to gaseous state it absorbed some heat or energy from surrounding that decrease the temperature of surrounding and causes cooling effect. One of the live example is sweating. In hot summer days, sweat evaporate causes cooling effect that balance the temperature of body.

What is meant by specific latent heat of vaporization of water is 2.26mj kg?

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.

What is specific latent heat of vaporization?

The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. Each substance has two specific latent heats: latent heat of vaporisation (the amount of energy needed to evaporate or condense the substance at its boiling point)

What is Latent of vaporization?

Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.

What is latent heat of vaporization of water class 10?

The latent heat of vaporization of a given liquid is the heat required to convert one kilogram of the liquid into vapour at its boiling point without any change of temperature. It is measured in joule per kilogram. The latent heat of vaporization of water is 2260 × 103 J/kg.

What is the cause of latent heat?

Sensible heat causes change in temperature due to contact with colder or warmer air of surfaces . Latent heat is the energy absorbed by or released from a substance during a phase change from a gas to a liquid or a solid or vice versa.

What is the formula of latent heat?

Answer: The latent heat is given by the equation: Q= m L. substituting the value of m, and the specific latent heat. Q= 0.5 Kg * 334 KJ/Kg = 167 KJ = 167000 J. This is the amount of energy released when water is melting at 0 °C.

What is latent heat of fusion of 1kg water?

For example, the latent heat of fusion of one kilogram of water, which is the amount of heat energy that must be supplied to convert 1 kg of ice without changing the temperature of the environment (which is kept at zero degrees celsius) is 333.55 kilojoules.

What is the the importance of latent heat?

Latent heat plays a very important role in thunderstorms and hurricanes . Clouds form when warm air rises and the water vapor it contains condenses onto particles called cloud condensation nuclei. At that point the air becomes saturated. When this air first begins to rise, the water vapor is in the gaseous phase.
