Specific latent heat of liquid nitrogen

WebIn this experiment you are to measure a thermal property of nitrogen; its latent heat of vaporization. Heat is a form of energy. The heat energy, Q, which must be added to a body … WebCarefully transfer the aluminum block from the liquid nitrogen into the water in the calorimeter, and replace the cover. Stir the water until the temperature reaches equilibrium at T 3. Record T 3. The heat gained by the aluminum as it warms up to T 3 is equal to the heat lost by the water and calorimeter cup and stirrer in cooling to T 3. Thus:

Latent Heat of Vaporization of Liquid Nitrogen (General Physics)

WebThe latent heat of vaporization is the amount of heat needed to cause a phase change between liquid and gas. L f and L v are coefficients that vary from substance to substance, depending on the strength of intermolecular forces, and both have standard units of J/kg. See Table 11.3 for values of L f and L v of different substances. WebLiquid nitrogen is a colorless, odorless and tasteless uid which boils at 77 K ( 196 C), and is formed by cooling and increasing pressure on air which is predominantly N 2 . Web0.5kg of ice at -5degC is put into a vessel containing 2kg of water at 15deg C and mixed together, the result being a mixture of ice and water at 0degC.Calculate the final masses of ice and water, taking the water equivalent of the vessel as 0.15kg.The specific heat of ice is 2.04kJ/kg/K and the latent heat of fusion is 335kJ/kg. •. cnpj moto remaza

WebSome coolants are used in both liquid and gas form in the same circuit, taking advantage of the high specific latent heat of boiling/condensing phase change, ... Liquid nitrogen, which boils at about -196 °C (77K), is the most common and least expensive coolant in use. 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 ...
