Answer : The specific heat of unknown sample is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of unknown sample = ?
= specific heat of water =
= specific heat of copper =
= mass of unknown sample = 72.0 g = 0.072 kg
= mass of water = 203 g = 0.203 kg
= mass of copper = 187 g = 0.187 kg
= final temperature of calorimeter =
= initial temperature of unknown sample =
= initial temperature of water and copper =
Now put all the given values in the above formula, we get
Therefore, the specific heat of unknown sample is,
