Lab Report: Specific Heat

Introduction These dolphins are for measuring specific heat. Specific heat, also called heat capacity, is the amount of heat per unit heat quantity necessary to raise the temperature by 1 ° C. Variations in the relationship between heat and temperature are typically expected in the form shown. This relationship does not hold if a phase change occurs because the heat added or removed during the phase change does not change the temperature. The molar specific heat of most solids above room temperature is nearly constant, consistent with Dulong and Petit's law.

The purpose of this experiment was to determine the identity of the unknown metal and to demonstrate whether the law of thermodynamics is correct when determining this identity. Using specific water permissible (4186 J / kg · ° C), the heat flow between two different water sets can provide useful data to determine the identity by conduction through unknown metals. Heat transfer can be calculated to approximate the specific heat of unknown metal. The characteristic of the unknown metal is aluminum. It can be inferred from the appearance of an unknown metal whose color resembles aluminum and is lightweight and shiny. When determining unknown metal, the law of thermodynamics holds. In order to generate heat flow during the experiment, it is necessary to apply the law of thermodynamics.

First we weigh unknown metals. Then we use unknown metal and heat it to about 100 degrees Celsius. Next, measure a large amount of water in the calorimeter, and put the heated metal in it. Record the initial and final (equilibrium) temperatures of water and metal. From these data, the specific heat and molecular weight of the metal can be calculated. Theory: It takes 18 joules to heat 1 gram of water to 1 ° C. In fact, the specific heat of water is a very important part of calorimetry and thermodynamics. The idea behind this laboratory is that you can determine the specific heat of the metal in the calorimeter if you know the calorimeter and the heat of the beginning and the end of the water in the metal and know the quality of the water and the quality of the metal about it
