The Heat Capacity of a substance is a quantity indicating the degree of difficulty of the substance hatco corporation to experience changes in temperature on the heat supply. It can be interpreted as an effect of thermal inertia.
From here it is easy to infer that increasing the mass of a substance, increase its heat capacity, thereby increasing the difficulty of the substance to change its temperature. An example of this can be seen in coastal cities where the sea acts as a great thermostat regulating temperature variations.
Water is a substance with a high heat capacity, it is shown as in the experiment can be viewed hatco corporation as having high energy absorption capacity, that is slow to heat up and cool down. Measurement of heat capacity to measure the heat capacity under certain conditions it is necessary to compare the heat absorbed by a substance (or system) with the resulting increase in temperature. The heat capacity is given by: where: C is the heat capacity, which generally will be a function of the state variables. Q is the heat absorbed by the system. Δ T the temperature variation hatco corporation is measured in SI units J / K (or in cal / C). The heat capacity hatco corporation (C) of a physical system depends on the amount of substance hatco corporation or mass of the system. For a system consisting of a single homogeneous material specific heat or heat capacity is further defined specific c from the relationship: where: C is the heat capacity of the body or system hatco corporation c is the specific heat or specific heat capacity m the mass of substance considered from the above relationship is easy to infer that increasing the mass of a substance, its heat capacity increases as the thermal hatco corporation inertia is increased, thereby increasing the difficulty of the substance to change its temperature. An example of this can be seen in coastal cities where the sea acts as a great thermostat regulating temperature variations. Formal approach of heat capacity Be a thermodynamic system in state A. Heat capacity C c associated with elemental c quasistatic defined process starting at A and ends at state B as the limit of the ratio of the quantity of heat Q absorbed by the system and the temperature increase Δ T that experienced when final state B tends to be confused with the initial A. Where, is a parametrized curve by temperature, which represents hatco corporation the path followed in phase space during c. The heat capacity is thus a thermodynamic variable and is well defined at each state of balancing between the system (the sign indicating that no function Q whose differential is precisely ie is one-way inaccurate).

These are between 500 and 1000 kcal / m C. Then there is another group that goes from 300 to 500 kcal / m C among the most common materials in actual construction, such as brick, concrete, wood, rock gypsum boards and stones are located sandstones. In a last group is (3-35 kcal / m C), thermal mass and insulation glass wool, mineral wool, expanded polystyrene and polyurethane foam by its "low hatco corporation density" because they contain much air have very low heat capacity but serve as thermal hatco corporation insulation. A special case is the air (0.29 kcal / m K and 1.214 J / m K), which serves as a means to transport heat in passive systems but not to store heat inside.
His unit in the SI system is the joule per kilogram kelvin, whose notation is J / (kg K). Quite the technical system unit is also used, the kilocalorie per kilogram degree Celsius and its notation is: kcal / kg C.
