A 50.0g sliver spoon at 20.0 degrees celsius is placed in a cup of cofee at 90.0 degrees celsius. How much heat does the spoon absorb from the cofee to reach a temperature of 89.0 degrees celsius?

Please explain...
Answered by drwls
They don't tell you the mass of the coffee, but you know the mass of the spoon. The heat lost by the coffee equals the heat absorbed by the spoon. Call it Q
Q = (spoon mass) x (silver specfic heat) x (temperature rise of spoon)

The specific heat of silver is 0.234 Joules/(grams degC)
