Rare Silver
A coin dealer, offered a rare silver coin, suspected that it might be a counterfeit nickel copy. The dealer he?
A coin dealer, offered a rare silver coin, suspected that it might be a counterfeit nickel copy. The dealer heated the coin, which weighed 15.0 g to 100°C in boiling water and then dropped the hot coin into 23.0 g of water at T = 16.5°C in an insulated coffee-cup, and measured the rise in temperature. If the coin was really made of silver, what would the final temperature of the water be (in °C)? (for nickel, s = 0.445 J/gC)
Let UNITs guide you; always USE THEM in your calculation to prevent errors
Specific Heat silver = 0.232 J/g.K
Specific heat water = 4.186 J/g.C
heat released from the coin = (15.0 g * 0.232 J/g.C) * (100-T)C = ??
heat gained by water = (23.0 g * 4.186 J/g.C) * (T-16.5)C = ??
SOLVE for T
Basic mathematics is a prerequisite to chemistry – I just try to help you with the methodology of solving the problem.
