Question

during the calorimetry experiment why didnt you use ice or metals to cool down you water? i.e. why is using ice problematic for the exiperment and equipment you had access to and why is using metals not feasible for the experiment? during the calorimetry experiment why didnt you use ice or metals to cool down you water? i.e. why is using ice problematic for the exiperment and equipment you had access to and why is using metals not feasible for the experiment? during the calorimetry experiment why didnt you use ice or metals to cool down you water? i.e. why is using ice problematic for the exiperment and equipment you had access to and why is using metals not feasible for the experiment?

Explanation / Answer

we cant use the ice because it will take some energy for the ice to get convert from solid to liquid which is enthalpy of fustion which will also take time and there will only be a small change in temperature or sometimes there may not be any change in temperature as the heat from water will be used up in melting the ice so it is difficult to calculate the temperature change and hence we cant use ice

and specific heat capacity of metal is very low and the temperature of metal changes more for even small amount of change when compared to water hence we cannot use the metal also
