    Experiment to measure the latent heat of vaporisation of water Theory Latent heat of vaporisation is when a liquid is heated enough to start boiling‚ at this point‚ even if the source of heat keeps heating the liquid‚ the liquid’s temperature will not rise any further until all of the liquid is converted to gas. For example‚ if water is boiling in a kettle‚ and the kettle is left on whist the water is boiling‚ the water’s temperature will not exceed 100°C because all the heat energy from the kettle is

    Heats of Reaction Lab Report Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation. NaOH(s) ( Na+(aq) + OH-(aq) ΔH = -10.6kcal/mol NaOH(s) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -23.9kcal/mol Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -13.3kcal/mol Background: Energy changes occur in all chemical reactions; energy is either absorbed or released. If energy is released in

    Vapor Pressure and Heat of Vaporization Introduction: ​Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. ​If the temperature inside
