temperature of the coffee cup after adding gold
Not what you're looking for?
A jeweler heats 60 g of gold (about 2 oz) almost to melting, 1000 degrees Celsius and drops it a cold cup of coffee to heat it up. If the cup has 200 ml of liquid in it (treat it as pure water) and is at 25 degrees Celsius before the hot gold is dropped in, estimate the temperature after the gold has been added. The specific heat capacity of gold is 0.13J/g/K. Water has a specific heat capacity of 4.2 J/g/K. Remember that the density of water is about 1.0g/cc and that 1 cc = 1 ml.
Note that 1 K = 1 degree Celsius.
