if you have 380.0mL of water at 25.00 degrees Celsius and add 140mL of water at 95.00 degrees Celsius, what is the final temperature of the mixture? Use 1.00 g/mol as the density of water.
heat gained by cool water + heat lost by warm water = 0
[mass cool H2O x specific heat x (Tfinal-Tintial)] + [mass warm water x specific heat x (Tfinal-Tinitial)] = 0
Solve for Tf.
How much heat is required to convert 72.4 of ethanol at -136 to the vapor phase at 78 ?
