# Metal Heating

Given that:

Initial temperature of metal: 20c

Final temperature of metal: 100c

Initial temperature of water from calorimeter: 20c

Final water temperature from calorimeter: 28c

1. What is estimate of specific heat for metal? (use 1 cal/gmÂ°C for water)

2. What is estimate the atomic weight of metal?

#### Solution Preview

1) Let specific heat for metal = s cal/gm/degree C

Hence, Heat energy per unit mass:

(T1f - T1i)*s1 = ...

#### Solution Summary

Specific heat for metal = s cal/gm/degree C,

Hence, Heat energy per unit mass is (T1f - T1i)*s1 = (T2f - T2i)*s2 where, T represents temperature, and i and f stand for initial and final .
