Equal 0.400-kg mass of lead and tin at 60 degrees celsius are placed in 1kg of water at 20 degrees celsius.
a) what is the equilibrium temperature of the system?
b)if an alloy is half lead and half tin by mass, what specific heat would you anticipate for the alloy?
c) how many atoms of tin are in 0.400kg of tin and how many atoms of lead are in 0.400kg of lead?
d) divide the number of tin atoms by the number of lead atoms and compare this ratio with the specific heat of tin divided by the specific heat of lead. what conclusion can be drawn?
