Question #e3382

Answer 1

I would use the heat exchanged as `Q=mCDeltaT` where:
`m` is the mass;
`C` is the specific heat;
`DeltaT=T_f-T_i` is the variation of temperature (final and initial).
We can relate the heat exchanged by the two substances as:
`Q_(water)+Q_(tungsten)=0` or
`200*4.18(21.2-20)+100*C_(tung)(21.2-100)=0`
`C_(tung)=1003.2/7880=0.13` J/g Celsius
