Wärmeaufnahmefähigkeit

Wärmeaufnahmefähigkeit, also known as heat capacity, is a physical property of a substance that describes the amount of heat energy required to raise its temperature by one degree Celsius or one Kelvin. It is an intrinsic property of a material, meaning it is independent of the amount of the substance. The unit for heat capacity is typically Joules per Kelvin (J/K) or Joules per kilogram-Kelvin (J/kg·K), where the latter is referred to as specific heat capacity. Specific heat capacity is the heat capacity per unit mass of a substance. Substances with high heat capacity can absorb a large amount of heat with only a small increase in temperature, while substances with low heat capacity will experience a significant temperature rise with the same amount of heat input. This property is crucial in various scientific and engineering applications, such as thermal insulation, climate regulation, and the design of heating and cooling systems. Water, for instance, has a remarkably high specific heat capacity, which plays a significant role in moderating Earth's climate. Conversely, metals generally have lower specific heat capacities, allowing them to heat up and cool down more quickly. The heataufnahmefähigkeit of a substance is a key factor in understanding how it interacts with thermal energy.
