Specific heat capacity of skin

WebSpecific Heat (J/kg*K) Specific heat measures how easy or difficult it is to raise the temperature of a product. In high-temperature applications, where regulating temperature is critical, this measurement shows what products will perform the best. Ceramics have exceptional performance when it comes to high specific heat requirements ... WebMay 13, 2015 · When the skin at the base of the thumb is at 33 °C, the threshold for detecting an increase in temperature is 0.20 °C and is 0.11 °C for detecting a decrease in temperature. The rate that skin temperature changes influences how readily people can detect the change in temperature.
