How much heat must be added to 26.3 g of solid white phosphorus, P4, at 14.4°C to give the liquid at its melting point, 44.1°C? The heat capacity of solid white phosphorus is 95.4 J/(K∙mol); its heat of fusion is 2.63 kJ/mol. Heat = ____ J
How much heat in joules must be added to 0.797 kg of beryllium to change it from a solid at 890°C to a liquid at 1285°C (its melting point)? For beryllium: 14 = 1.35x106J/kg, Ly = 3.24x107J/kg, c = 1820 J/kg Cº Number: Units:
Heat is added to a substance at a constant rate. The substance starts as a solid and is melted; the liquid is heated and vaporized; finally, the vapor is heated. This process is shown in the graph. The latent heat of fusion can be found by > Temperature - Time — >
How much water remains unfrozen after 58.1 kJ is transferred as heat from 423 g of liquid water initially at its freezing point? The latent heat of fusion is 333 kJ/kg.
How much water remains unfrozen after 52.8 kJ is transferred as heat from 326 g of liquid water initially at its freezing point? The latent heat of fusion is 333 kJ/kg. Number Units
4. The other phase change that can happen is liquid to gas. Similar to the phase change of solid to liquid, the temperature of the system does not change. All of the energy goes into the phase change. Only now instead of the latent heat of fusion, we have the latent heat of vaporization: Q = mly How much heat must be added to 3.8 kg (1 gallon) of water for half of it to be changed into gas? The...
