Because this energy enters or leaves a system during a phase change without causing a temperature change in the system, it is known as latent heat (latent means hidden). The three phases of matter that you frequently encounter are solid, liquid and gas (see Figure 11.8).
Definition av latent heat. the heat that is released or absorbed accompanying a change of state or of phase. Liknande ord. latent · latently · latentness · latent
Heat released or absorbed when a substance changes state without a change in temperature. Latent Heat Definition In other words, when i substance such as water is boiled, the temperature of the water does not change when it’s undergoing the phase change to a gas. Only when the water is in a gaseous state does the temperature start to increase. Fördomarna ligger latent men ingen reagerar när någon går över självklara men osynliga gränser. Men det där är något som finns latent hos Kraftwerk. Det visar sig att det finns en latent konflikt mellan de två böckerna.
Freud helped people find meaning in their dreams by developing the concepts of latent and manifest content. Freud believes that uncovering the meaning of his patients’ When it comes to small heating systems, electric and infrared heaters are among the most popular choices for small rooms or for warming up a small space in a larger room. Small heaters mainly serve to supplement the central heating system o Thanks to modern technology, today’s houses have evolved beyond their basic role of providing shelter. They have become total environments that sustain, refresh, and provide us with a high level of healthful comfort.
When a substance changes phase, that is it goes from either a solid to a liquid or liquid to gas, the energy, it requires energy to do so.The potential energy stored in the interatomics forces between molecules needs to be overcome by the kinetic energy the motion of the particles before the substance can change phase. Heat-of-fusion storage materials for low temperature latent heat storage in the temperature range 0-120°C are reviewed. Organic and inorganic heat storage materials classified as paraffins, fatty acids, inorganic salt hydrates and eutectic compounds Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.
Latent heat, also called heat of transformation, is the heat given up or absorbed by a unit mass of a substance as it changes from a solid to a liquid, from a liquid to

The (latent) heat of vaporization (∆H vap) also known as the enthalpy of vaporization or evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance, to transform a given quantity of the substance into a gas.. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. The heat of vaporization diminishes with increasing
Latent Heat Early Developments of the Concept. English scientific expert Joseph Black presented the idea of latent heat somewhere Types of Latent Heat Transfer. Lets us discuss some the different types of latent heat that can occur.
