Physics Lab Report – Specific Heat Capacity

Presentation and methodology (Planning A & B)

Aim: The present experiment is to find the specific heat capacity of aluminium.

In this experiment, we are going to use a calorimeter (a solid metal block of aluminium). And we are going to expose it to different temperatures and measure the difference in temperature over time.

We will also measure the changes in electric properties from the heater over time: Volts and Amperes. In order to get more precise data, we are going to repeat this experiment twice with different power and the second trial will use stronger voltage. The reason that we

In order to get more precise data, we should definitely insulate the calorimeter to minimize its heat lost to the surroundings. For instance, we may place bubble wrap, foil or Styrofoam around the calorimeter.

To obtain more accurate results in the future, a good idea may be to perform the experiment more than twice. Even if the heat loss variable is set aside after more than one experiment, we might get more reliable data by overcoming the variations we have observed in heat transmission between the heater and calorimeter.
