🔥 Specific heat capacity of aluminum. Table of specific heat capacities. 2022-11-06 (2023)

The specific heat capacity of a substance is a measure of how much energy is required to raise the temperature of a given amount of that substance by a given amount. In other words, it is a measure of the substance's thermal resistance, or its ability to absorb or release heat. The specific heat capacity of a substance is usually denoted by the symbol "c" and is typically measured in units of joules per gram Kelvin (J/g-K).

Aluminum is a metal known for its high specific heat capacity. This means it is able to absorb a large amount of heat without experiencing a significant change in temperature. The specific heat capacity of aluminum is approx. 0.902 J/g-K. This value is relatively high compared to many other materials, which means that aluminum is a good conductor of heat and can dissipate heat effectively.

One of the reasons for aluminum's high specific heat capacity is its atomic structure. Aluminum atoms are arranged in a face-centered cubic crystal structure, which allows a large amount of lattice energy to be stored in the material. Lattice energy is the energy required to separate the atoms in a solid material and is related to the strength of the bonds between atoms. When heat is applied to aluminum, the lattice energy is converted to kinetic energy, increasing the temperature of the material.

Aluminum's high specific heat capacity makes it an excellent material for use in a wide variety of applications. For example, aluminum is widely used in the manufacture of heat exchangers, designed to transfer heat from one fluid to another. It is also used in the manufacture of cookware such as pots and pans due to its ability to distribute heat evenly. In addition, aluminum is widely used as a heat sink in electronic devices due to its ability to effectively dissipate the heat generated by the device.

In summary, the specific heat capacity of aluminum is a measure of the substance's ability to absorb or release heat and is an important property to consider in various applications. Aluminum has a relatively high specific heat capacity, making it an excellent material for use in heat exchangers, cookware, and as heat sinks in electronic devices.

It is shipped with dissolved acetone in gaseous form. Dulong – Petit Limit also explains in the last column why large deviations from R in solids at standard temperatures are usually due to low atomic weight plus high bond strength as in diamond, resulting in some vibrational modes having too much energy to be available store its thermal energy at the measured temperature.
