Specifications:

• Apparatus of Measuring Specific Heat Capacity, is designed with a few innovations compared with the traditional experimental methods and experimental instruments. In the aspect of experimental method, the cooling conditions of the sample are no longer only natural cooling in room temperature environment, ut also use a fan to create forced convection for cooling environment. The advantages and disadvantages of the two cooling conditions can be compared and analyzed. In the aspect of experimental device, the heating device is a PTC heating plate working at a safe voltage with temperature limiting. A temperature sensor of PT100 resistance is used to replace the traditional Copperconstantan thermocouple that needs an icy reference end to work. The sample chamber is changed from the traditional up and down vertical structure to the left and right horizontal structure. The heater movement in the sample chamber is also changed from up and down to left and right, making the experimental operation more convenient.
• This apparatus takes copper as the standard sample and measures the specific heat capacity of iron and aluminum samples at 100 °C under two different cooling environments, i.e. forced convective cooling and natural cooling, enables students to understand the relationship between the cooling rate of metal and the cooling environment, and master the experimental method of measuring specific heat capacity of metal by cooling.
• This experimental apparatus mainly consists of a main electric unit, a heater, a sample chamber, a cooling fan, a PT100 platinum resistance, and so on. Using this apparatus, the following experiments can be performed:

1. Learn to measure temperature using PT100 platinum resistance;

2. Under forced convective cooling, measure specific heat capacity of iron and aluminum samples at 100 °C;

3. Under natural cooling, measure specific heat capacity of iron and aluminum samples at 100 °C.
