A 100 x 102g brass block at 900SolutionmBCBTf TBi mWCWTf

A 1.00 x 10²-g brass block at 90.0

m_BC_B(T_f - T_Bi) + m_WC_W(T_f - T_Wi) = 0

T_f = (m_BC_BT_Bi + m_WC_WT_Wi) / (m_BC_B + m_WC_W)

= [(0.100 kg)(376 J/kg.K)(90.0

A 1.00 x 102-g brass block at 90.0SolutionmBCB(Tf - TBi) + mWCW(Tf - TWi) = 0 Tf = (mBCBTBi + mWCWTWi) / (mBCB + mWCW) = [(0.100 kg)(376 J/kg.K)(90.0
