Question

A piece of unknown metal with mass 68.6 g is heated to an initial temperature of 100 °C and dropped into 84 g of water (with an initial temperature of 20 °C) in a calorimeter. The final temperature of the system is 52.1°C. The specific heat of water is 4.184 J/g*⁰C. What is the specific heat of the metal?

Answer 1

q= (m)(cp) (delta T)

cp=-q/23.8 (32.5-100.0) ( q is negative because heat was lost)
