Latent heat can either be: The heat absorbed if the change involves solid to liquid or liquid to gas; The heat released if the change involves gas to liquid or liquid to solid. From this Black developed the idea of 'specific heat'. This measured the amount of heat required to raise the temperature of a substance by a specified number of degrees. Latent heat is the heat energy per mass unit required for a phase change to occur. If we think about substances at a molecular level, gaseous molecules have more vibration than liquid molecules.
The latent heat of fusion of ice is ×10 5 joules per kilogram (or ×10 5 j/kg). Latent Heat of Vaporization (liquid to gas change): The latent heat of vaporisation of a liquid is the quantity of heat in joules required to convert 1 kilogram of the liquid (at its boiling point) to vapour or gas, without any change in temperature.

Heat capacity (C) is the heat energy required to raise the temperature of a body by. one degree (o C or K). The units of heat capacity are Joules per degree. Since Kelvin and Celsius degrees are equivalent the units are: JK-1 or JC Specific heat capacity (c) is the heat energy required to . In this video, we look at heating and cooling curves. We look at what happens to substances when we heat them and the changes of state from graphs. Image credits:

The Discovery of Specific and Latent Heats Douglas McKie, Niels Hugh de Vaudrey Heathcote Snippet view - Douglas MacKie, Niels Hugh de Vaudrey Heathcote Snippet view - Black and also Wilcke discovered latent and specific heat (Black was helped by Fahrenheit’s earlier researches.) Black improved on the ‘method of mixtures’ (already used by Brook Taylor) and defined a quantitative measure for heat.
He proclaimed that separate bodies strive to reach an equilibrium of temperature rather than heat. Discovery of specific and latent heats.

The Discovery of Latent Heat Years ago Stefan Emeis Bärenmühl Weilheim, Germany @ Introduction. Latent heat plays a decisive role in the global energy balance of our planet. Heat absorbed or released as the result of a phase change is called latent heat. There is no temperature change during a phase change, thus there is no change in the kinetic energy of the particles in the material.
The energy released comes from the potential energy stored in. Background. When energy in the form of heat, is added to a material, the temperature of the material that temperature, in units of degrees Celsius (°C) or Kelvin (K), is a measure of how hot or cold a substance is, while heat, in units of joules (J) or calories (cal), is a.
Explorations: The Discovery and Science of Latent Heat Adam Hart-Davis, in “James Watt and the Lunaticks of Birmingham,” Science (April 6, ): 55–56, puts the discovery of latent heat in the scientific context of the explosion of scientific knowledge in the middle of the eighteenth century.
He also tries to lay to rest the idea that James Watt “invented the steam engine” by. Discover the best Latent Heat books and audiobooks. Learn from Latent Heat experts like Frontiers and Frontiers.

Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing.
Latent heat storage is a popular research area with industrial and domestic applications, such as energy recovery of air-conditioning and underfloor electric heating by using a phase changing material.
Figure shows the charging and discharging operations with appropriate valves and temperature profiles for countercurrent latent heat storage with subcooling and sensible heating. Joseph Black (16 April – 6 December ) was a Scottish physicist and chemist, known for his discoveries of magnesium, latent heat, specific heat, and carbon dioxide.
He was Professor of Anatomy and Chemistry at the University of Glasgow for 10 years from Fields: Medicine, physics, chemistry. The amount of heat that can be transferred to an object is limited by its specific heat. This is defined quantitatively with worked examples.
In addition, the amount of heat required to transform matter from solid to liquid to gas is also defined quantitatively in terms of the latent heat of fusion and vaporisation. and method for experiments, which are described in most text books).
Latent Heat The word ‘latent’ was first used by Joseph Black ( – ), a French-born Scottish chemist noted for his fundamental work on latent heat and specific heat as well as his discovery of carbon Size: KB.
Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process that is specified in some example is latent heat of fusion for a phase change, melting, at a specified temperature and pressure.
  The term was introduced around by Scottish chemist Joseph is derived from the Latin latere (to lie hidden). (1) Solid-liquid, concerns the “latent heat of fusion” (denoted L f): it is the heat required to change a unit mass from solid to liquid at the same temperature f There are 2 distinct phase changes: Latent heat (2) Liquid-gas, concerns the “latent heat of vaporization” (denoted L v): it is the heat.
Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature.
Examples are latent heat of fusion and latent heat of vaporization involved in phase changes, i.e. a substance condensing or vaporizing at a specified temperature and pressure.Latent heat is the heat absorbed or released as the result of a phase change.
This temperature change during a phase change is due to the energy released from the potential energy stored in the bonds between the particles, and not due to the energy release from the kinetic energy of the particle.
Check out the latent heat of fusion and.Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance. It could either be from a gas to a liquid or liquid to solid and vice versa.
Latent heat is related to a heat property called enthalpy. However, an important point that we should consider regarding latent heat is that the temperature.
