27) A sаmple оf metаl hаving a mass оf 36.0 g, initially at 98.2 оC, is placed in 92.3 g of water at 21 oC. The final temperature of the water and metal is 23.4 oC. Calculate the specific heat of the metal (Cs).  [∆T = T2 – T1]              [Spec. Heat of water (Cs) = 4.184 J/g.oC]                 [q = m * Sp. Heat *∆T]    Question 27.png
