A 10.0 g sample of water at 50°C and 10.0 g sample of iron at 10°C are placed in a beaker together. What will happen to the temperature of the water?
Final temperature of water will be 46.11 degrees.
Energy in water
x will be the final temperature (For specific heat coefficients: http://www.kentchemistry.com/links/Energy/SpecificHeat.htm):
The final temperature of water and iron will be the same.
