HOW TO FIND SPECIFIC HEAT CAPACITY OF THE METAL?
Asked by shisham | 20 Mar, 2010, 10:37: AM
answered-by-expert Expert Answer

Specific heat capacity of a substance = Heat provided/[(mass)(change in temperature)]

Heat provided = (Specific heat)(Mass)(change in temperature)

Using this we can calculate heat taken up by water,

=(4200)(0.35)(30-23) = 10290 J

Now using the first equaton, we can calculate the specific heat capacity of metal. Note that the tempreature of metal decreases from 135 °C to 30 °C.

= (10290)/[(0.2)(135-30)] = 490 J/kg °C
