a.When a metal at higher temperature is transfer to water at a lower temperature, heat is inevitably lost to the calorimeter. Will this unmeasured heat loss increase or decrease the calculated value of the specific heat of the metal?

b.Explain why the extrapolated temperature is used to determine the maximum temperature of the mixture rather than the highest record temperature in the experiment.
