Expert Answer
Heat loss by M2 kg of steam, QS = M2×L+M2×C1*(100-t2)
Heat Gain by Calorimeter QC = M1×C1×( t2 - t1)
Heat Gain by Water QW = M×C2×( t2 - t1)
QS = QC +QW
M2×L + M2×C1×(100 - t2) = M1×C1×(t2 - t1)+M×C2×( t2 - t1) = (M1×C1+M×C2)×[t2 - t1]
L = [ (M1/M2)×C1+( M / M2)×C2 ] ×(t2 - t1) - C1×( 100 - t2)
