Answer 1

mass of metal piece(m)=959 V T Initial Temperature of unknown metal 150C Specific heat of metal (S.) = ? Water (m2) 42 gir 2 mass of Specific heat of water (S2) - 4+186 Temperature of water (1)=216

When thetal and water are mined Let To be the final Temperature of misiture. By principle of Calorimetry Heat lost by = Heat gainebby metal Water ms, t, -TP) = m_S244-72)

m₂ & Go- 2 ร of m CT - T Here In the Image final Temperature of the mixture is missing substituting the values of my my giftist We get the specific heat of metal Sz
