from an m=mass of chlorometer and s= specific is equal to specific heat for the chloro remitter material the water equivalent of the calorimeter is
Answers
In a reaction the quantity of heat that raises the temperature of some substance by some amount, the same quantity of heat can simultaneously raise the same temperature of a certain mass of water. The mass of water is then termed as water equivalent.
Principle:
The heat change associated with a chemical reaction can be studied with the help of the calorimetric techniques. In a specific reaction the quantity of heat that raises the temperature of some substance by some amount, the same quantity of heat can simultaneously raise the same temperature of a certain mass of water assuming the specific heat of water to be 1 calorie per gram. The mass of water is then termed as water equivalent.
Important steps to follow:
1. 50mL water is taken in a beaker and heated to about 60o C.
2. Transfer it to a calorimeter fitted with stirrer and thermometer.
3. Temperature is noted at every half minute till it become constant.
4. Add 50mL of cold water, whose temperature is previously noted, to the calorimeter.
5. Note the temperature, in every half minute, till it become a constant.
6. Plot a graph with temperature on Y axis and time on X axis.
