Heat capacity The amount of heat required to raise the temperature of a substance by a given amount. If given on a per unit mass basis, this is called the specific heat capacity or specific heat. 

Specific Heat Capacity the amount of heat required to raise the temperature of an object by 1 degree Celsius Spectator Ions ions that do not take part in a chemical reaction... 

Heat is a form of energy that flows from warmer objects to cooler objects. But how much heat can an object hold If objects have the same heat content, does that mean they re the same temperature You can measure different temperatures, but how do these temperatures relate to heat flow These kinds of questions revolve around the concept of heat capacity, the amount of heat required to raise the temperature of a system by 1°C, or 1 K. 

HEAT CAPACITY. The amount of heal necessary, to raise the temperature of a sysiem, entity, or substance by one degree of temperature. It is most frequently expressed in calories per degree cenrigrade or Btu per degree Fahrenheit, if the mass of a substance is specified, then certain derived values of the heal capacity can be obtained, such as the atomic heat, molar heut. or specific heat. 

Heat capacity The amount of energy required to raise the temperature of a substance by 1° C. 

Molar heat capacity The amount of heat necessary to raise the temperature of one mole of a substance one degree Celsius with no change in state usually expressed in kJ/mol-°C. See Specific heat. 

Heat capacity the amount of energy required to raise the temperature of an object by one degree Celsius. (9.4) Heat of fusion the enthalpy change that occurs to melt a solid at its melting point. (16.10)... 

CALORIMETRY (SECTION 5.5) The amoimt of heat transferred between the system and the surroundings is measured experimentally by calorimetry. A calorimeter measures the temperature change accompanying a process. The temperature change of a calorimeter depends on its heat capacity, the amount of heat required to raise its temperature by 1 K. The heat capacity for one mole of a pure substance is called its molar heat capacity for one gram of the substance, we use the term specific heat. Water has a very high specific heat, 4.18 J/g-K. The amount of heat, q, absorbed by a substance is the product of its specific heat (Cj), its mass, and its temperature change q = Cj X m X AT. 

The change in enthalpy, AH, as you may find in a physical chemistry textbook, under the section on first law of thermodynamics, equals q, the heat. Check Problem 3.1, with the mountain climber in cold rain, and you will find that heat is expressed as a product of heat capacity, the amount of the substance, and the difference in temperatures ... 

The measured heat input divided by the temperature change defines the heat capacity, the amount of heat needed to raise the temperature of a given amount of a material by 1 K. At constant volume, the heat capacity CV is... 

How do we compute the energy of streams 1 and 2 We must convert temperatures to energy. From thermodynamics we learn that the change in internal energy is linearly proportional to the change in temperature. The proportionality constant is the product of the two quantities the mass and the heat capacity, the amount of energy needed to raise the temperature of 1 kg 1°C. Thus from thermodynamics we use the relation... 

Heat capacity the amount of heat necessary to increase the temperature of the tmit of material 1 K. 

We quantify heat with the equation q = m X X AT. In this expression, Cj is the specific heat capacity, the amount of heat required to change the temperature of 1 g of the substance by 1 °C. Compared to most substances, water has a very high heat capacity—it takes a lot of heat to change its temperature.
