From this experiment we can conclude that the specific heat capacity of copper = 391. 8353  1oo J approx. Possible errors: 1. Systematic Error in the measurement of variables in instruments such as the thermometer and the weighing scale. The extent is represented by the uncertainty. 2. Improper isolation may have led to the system trying to attain equilibrium with the atmosphere and thus reducing the overall final temperature of the system.

A lot of heat could be lost during the transfer of the solid metal block to the calorimeter 4. There could be parallax error while reading the thermometer. Possible ways of reducing such errors: 1. Usage of branded instruments to assure accuracy. 2. Using digital thermometers to prevent parallax error and reducing the uncertainty. 3. Making the transfer of the metal block quickly so that very less heat energy is escaped. To find the specific heat capacity of a solid by method of mixtures.

Materials Required: calorimeter, Thermometer (110 c), stopwatch, weighing machine. Background Theory: 1. Specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 Kg of that substance by c. 2. Thermal equilibrium is a state when the amount of heat given by one body to another is equal to the amount of heat energy given by second body to the first and the temperatures remain constant.
