45g of water at 50oC in a beaker is cooled when 50g of copper at 18oC is added to it - Physics - Calorimetry

Question

45g of water at 50oC in a beaker is cooled when 50g
of copper at 18oC is added to it the contents are
stirred till a final constant temperature is reached the specific
heat capacity of copper is 0 39Jkg-1K-1 state
the assumption used

Heat gained by copper=m×C×θ=50×0
39×(T-18)Heat lost by water=45×4
2×(50-T)Heat lost=Heat gained45×4
2×(50-T)=50×0 39×(T-18)9450-189 T=19
5 T-351208
5 T=9801Or T=470C (Approx)So the fnal temperature is 470C (Approx)

45g of water at 50oC in a beaker is cooled when 50g of copper at 18oC is added to it. the contents are stirred till a final constant temperature is reached .the specific heat capacity of copper is 0.39Jkg-1K-1.state the assumption used.

45g of water at 50^oC in a beaker is cooled when 50g of copper at 18^oC is added to it. the contents are stirred till a final constant temperature is reached .the specific heat capacity of copper is 0.39Jkg^-1K^-1.state the assumption used.
