AIM: 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 1˚ 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

Conclusion

± 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.
  1. 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.
  1. A lot of heat could be lost during the transfer of the solid metal block to the calorimeter
  1. 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.

    * Then I measured and noted down the temperature of the water being heated as T2 which was also the temperature of the metal block and then I removed the metal block and immediately immersed it into the water in the calorimeter and straight away covered the calorimeter in order to avoid any heat loss to the atmosphere.

    - 1 METHOD: i. I kept the metallic bob into the hot water bath to heat it. ii. During the bob was being heated by hot water bath I took an empty calorimeter and weighed it on the Top-pan balance. iii. I half filled the calorimeter with tap water and weighed it again. iv.

  2. Researching water turbine designs.

    The water enters the turbine by the spiral case that is designed to keep its tangential velocity constant along the consecutive sections and to distribute it peripherally to the distributor. This one has mobile guide vanes, whose function is to control the discharge going into the runner and adapt the inlet angle of the flow to the runner blades angles.
