Determination of specific heat
Capacity of a solid by electrical method

Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies, heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius, different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the internal temperature of a substance this depends on the mass and the material it’s self. To demonstrate specific heat capacity of a solid an experiment was carried out using 1kg aluminium mass and 1kg copper mass heat was conducted to the masses by

The reason for this is that copper’s molecules are more densely packed and so it is a good conductor of heat, and when 1 kg of each substance are compared visually it is easily seen that 1kg of copper mass is far smaller than 1kg of aluminium mass. Aluminium is more efficient at radiating or dispersing heat as it is less dense which also makes it a lighter material.
Overall this experiment has successfully reached its objectives however some errors have occurred as shown in the experimental errors where the experimental values do not match the actual values of the materials this could be caused by heat loss through the material which could be reduced with better insulation of the material. Further error could have been avoided in the first experiment by letting the heating element reach its maximum output before inserting it into the aluminium block as the warm up time is not taken into consideration in the first experiment; this was not a factor in the second experiment as the heating element was immediately placed into the copper block and was at its maximum
