Specific latent heat of liquid nitrogen
WebLatent heat is measured in units of J/kg. Both Lf and Lv depend on the substance, particularly on the strength of its molecular forces as noted earlier. Lf and Lv are collectively called latent heat coefficients. WebApr 14, 2024 · For food products, the latent heat of fusion can be estimated as λ = Mwater × λw where λ = latent heat of fusion of food product (kJ/kg) Mwater = amount of water in product, or water content (decimal) λw = latent heat of fusion of pure water (~334 kJ/kg)

When calculating mass … WebConclusion The aim of this experiment was to determine the latent heat of vaporisation of nitrogen. This was done by heating liquid nitrogen with a resistor and relating the power transfer to the latent heat of vaporisation. The experiment yielded a value of 188 ± 22 kJkg¯¹. This is within the accepted value of 199 kJkg¯¹ [1] but it has a ...
WebNitrogen is an inert gas with many industrial applications. It is liquefied by cooling at -320.8 °F (-196 °C/77.15 K). It is mainly found in the atmosphere, where it accounts for 78 % by volume of the air we breath.

WebQuestion: Latent Heat of Vaporization of Liquid Nitrogen Introduction When heat is transferred to or from substance its temperature usually increases or decreases unless that substance is undergoing a change of phase (e.g., a solid is changed into a liquid phase or a liquid state is changed into its vapor phase). The change of phase occurs without … The terms ″sensible heat″ and ″latent heat″ refer to energy transferred between a body and its surroundings, defined by the occurrence or non-occurrence of temperature change; they depend on the properties of the body. ″Sensible heat″ is ″sensed″ or felt in a process as a change in the body's temperature. ″Latent heat″ is energy transferred in a process without change of the body's temperat…
WebDec 30, 2024 · Since the role of evaporation scales with the latent heat, this behaviour is likely to be more pronounced for polar liquids such as water, in which the latent heat of vaporization is an order of magnitude larger than for liquid nitrogen.
