a 410-g cylinder of brass is heated to 95.0C and placed in a calorimeter containing 335 g of water at 25C. The water is stirred, and its highest temp is recorded as 32C. From the thermal energy gained by the water, determine the specific heat of brass. The specific heat of water is 4.18 J/g•ºC.

Question

gebooors · Answer

Water gets energy E = 335 g * 4.18 J / g C * 7 C

Brass gives up same energy .

Spesific heat of Brass is E / ( m(Brass) * change of temperature of brass)

In the end temperature of water and Brass are same.
