What was the final temperature of the coins? [One-cent coins are made of a metal alloy - mostly zinc - with a specific heat capacity of 390 J/(kg*K).]

I know that:

Mass,coins=.615 kg

Mass,water=.244 kg

c=390 J/(kg*K)

Ti,water=20 C

I'm just not quite sure what equation to put them in...

**DrBob222**, Tuesday, December 4, 2007 at 12:30pmHeat lost by the coins + heat gained by the water = 0

mass x specific heat x (Tf - Ti) + mass x specific heat x (Tf - Ti) = 0

Tf is final T. Ti is initial T.

Post your work if you get stuck.
