    spring and summer is the principal melting energy source. Most operational procedures for snow melt prediction rely on ambient air temperature as the index of the energy available for melt. The temperature index is usually used to characterize the level of the energy balance because it is superior to other simple methods for the full energy balance at the snow surface. As long as snow remains bright‚ the sunshine bounces off and is not retained to cause any melting. Two factors other than sunshine

    The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

    Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated
