Specific Heat of Solids Object: To determine the specific heat of a given solid specimen. Theory: Thermal energy is an internal energy that consists of the kinetic and potential energies associated with the random motions of the atoms, molecules, and other microscopic bodies within an object.
In this experiment, students will find the specific heat of three “unknown” samples of metal. To do this, students will use their knowledge of thermodynamics to construct a calorimeter. Temperature is a measure of the average translational kinetic energy of the atoms or molecules of a substance.
Specific Heat (s): The quantity of heat liberated or absorbed when the temperature of 1.00 gram of a substance falls or rises 1.00°C. Specific heat is temperature (and phase) dependent. Thus one must know not only the substance but also the temperature range and whether a solid, liquid or gas is involved.
The simplest definition is that heat is a form of energy and this energy can be tapped to do useful work. How does heat become energy? Suppose we have a given mass of a substance, say, a glass of water. On a molecular level, (according to the Kinetic Theory of Matter) all molecules are in random motion at all times.
Einstein’s Theory of Specific heat of a solid In Einstein’s theory, the crystal lattice structure of a solid comprising N atoms can be treated as an assembly of 3N distinguishable one-dimensional oscillators. This assumption is based on that each atom is free to move in three dimensions. The energy level of harmonic oscillator is 𝐸 =(𝑛+ 1
In this experiment, you will determine the specific heat capacities of two different unknown metals by observing the transfer of heat from a heated piece of metal to a sample of water at room temperature.
The specific heat is an intensive property that describes how much heat must be added to a particular substance to raise its temperature. The heat capacity is an extensive property that describes how much heat energy it takes to raise the temperature of a given system.
