What is meant by latent heat of vaporization? This discussion on What is latent heat of vaporization ? is done on EduRev Study Group by Class 9 Students. Interestingly, the latent heat of vaporization is the amount of energy required to convert the liquid into vapor and vice versa. Specific Heat. Specific heat, heat of fusion and vaporization, Latent heat - Mechanical Properties of Fluids, L18 : Example latent Heat - Thermal Properties, Physics, Class 11, RD Sharma Solutions for Class 9 Mathematics, English Grammar (Communicative) Interact In English- Class 9, Class 9 Physics, Chemistry & Biology Tips & Tricks. In other words, these values are the units of heat per mass that are required to achieve the phase change. 7. Water has a high latent heat of vaporization, which is why steam burns are so dangerous. • The amount heat required to convert unit mass of liquid into its vapour state without change in its temperature called is latent heat of vaporization. It is expressed as kg/mol or kJ/kg. vaporization-when liquids turn into gas -happens at boiling point. You may need to download version 2.0 now from the Chrome Web Store. | EduRev Class 9 Question is disucussed on EduRev Study Group by 195 Class 9 Students. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. Latent heat of vapourisation is a physical property of a substance. ... - known as latent heat since it doesn't show up as a change in temp - when heat is changing during the same phase of matter the temp will change and kinetic energy increases. In the field of thermodynamics, the study of heat transfer and thermal effects is common. The Questions and When a material in liquid state is given energy, it changes its phase from liquid to vapour without change in temperature, the energy absorbed in the process is called latent heat of vaporization. Another way to prevent getting this page in the future is to use Privacy Pass. Cloudflare Ray ID: 5f89306caa6d7e13 Also known as enthalpy of vaporization, the heat of vaporization (∆H vap) is defined by the amount of enthalpy (heat energy) that is required to transform a liquid substance into a gas or vapor.It is measured in Joules … Is water vapour an ideal gas? The heat of condensation is defined as the heat released when one mole of the... Over 10 million scientific documents at your fingertips. It is due to the latent heat of vaporization that steam burns are considered to be so dangerous, as compared to burns caused by hot water. Here is the Latent Heat table which shows the latent heat of vaporization and change of phase temperatures for some of the common fluids and gases. Latent heat of vaporization is a physical property of a substance. It is expressed as kg/mol or kJ/kg. are solved by group of students and teacher of Class 9, which is also the largest student Your IP: latent heat graph. Apart from being the largest Class 9 community, EduRev has the largest solved Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics.The intensive properties c v and c p are defined for pure, simple compressible substances as partial derivatives of the internal energy u(T, v) and enthalpy h(T, p), respectively: The latent heat of vaporization is the thermal energy required for a liquid to vaporize to a gas or the amount that is released when a gas condenses to a liquid. 8. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. When a substance changes phase, the arrangement of its molecules changes, but its temperature does not change.
