High specific heat capacity example
WebMay 17, 2024 · By Alex Silbajoris. Because water can absorb and transfer heat well, the human body uses it to stabilize temperature. Water has a relatively high heat capacity, meaning it can absorb a lot of heat before its temperature rises. This trait allows the water in every cell of the human body to act as a buffer against sudden temperature changes. WebSpecific heat capacity. Heat capacity is a property that describes how much energy is needed to change the temperature of a material. Objects with a high specific heat capacity require a greater change in energy to change their temperature and vice versa for objects with a low specific heat capacity. Measured in units of Joules per Kelvin ...
