Specific Heat Capacity Testing Services

Specific heat capacity, also known as specific heat, is a property that quantifies the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius or Kelvin. It represents the substance’s ability to store thermal energy.

The units of specific heat capacity depend on the system of units used. In the International System of Units (SI), specific heat capacity is expressed in joules per kilogram per degree Celsius (J/kg·°C) or joules per kilogram per Kelvin (J/kg·K). Other common units include calories per gram per degree Celsius (cal/g·°C) in the CGS system.

Specific heat capacity testing measures the amount of energy required to raise the temperature of a substance per unit mass. It helps characterize a material’s ability to store thermal energy. During testing, a sample is subjected to controlled heating or cooling, and the resulting temperature change is measured. This data allows for the calculation of specific heat capacity. The information obtained is useful in designing efficient thermal management systems, selecting appropriate materials, and understanding phase changes. Specific heat capacity testing is commonly performed using calorimetry techniques. By accurately determining specific heat capacity, industries can optimize heat transfer, calculate energy requirements, and make informed decisions.

Specific heat capacity relates to a material’s ability to store heat energy, while thermal conductivity pertains to its ability to conduct heat. Specific heat capacity focuses on the amount of energy required to change the substance’s temperature, while thermal conductivity deals with the rate of heat transfer through the material.

The theory behind this specific heat capacity test is based on the conservation of energy. Specific heat capacity can be measured using different methods such as Laser Flash Apparatus (LFA), Differential Scanning Calorimeter (DSC), Transient Plane Source (TPS) and Transient Hot Wire (THW) techniques.
