Concept:Stirring in the method of mixtures makes the temperature uniform throughout the mixture.
Explanation:In this method, a hot body is placed in a cold liquid inside a calorimeter.
Heat flows from the hot body to the cold liquid until both reach a common temperature.
Continuous stirring mixes the warmer and cooler parts of the liquid thoroughly.
This prevents localised heating or cooling from affecting the thermometer reading.
As a result, the thermometer shows the true equilibrium temperature of the whole mixture.
This leads to a more accurate determination of the specific thermal capacity.
Answer:B. uniform distribution of thermal energy to all parts of the mixture
