You take a 25.00 g ice cube (temperature -20 EC) and place it in 225.00 g of water at 22 EC. What will the temperature of the water be when the ice cube has just melted. Assume the specific heat capacity for ice and water is 4.184 J/K@g. If you then heat the water from this temperature to 80 EC by burning methane (ÄHrxn= !890.31 kJ/mol), how many grams of methane would you have to use?
