Professor Al, from the chemistry department at AUT, introduces some of the fundamentals of thermodynamics; eat, work, internal energy, and heat capacity. The worked problem: A gold nugget at a temperature of 200 ºC is dropped into 100 g of water at a temperature of ºC. If the final temperature of the water is ºC, calculate a) how much heat is absorbed by the water b) how much heat is lost by the gold c) the mass of the gold nugget.
