Deflection Temperature Testing of Plastics. The deflection temperature is a measure of a polymer's ability to bear a given load at elevated temperatures. The deflection temperature is also known as the 'deflection temperature under load' (DTUL), 'heat deflection temperature', or 'heat distortion temperature' (HDT).
Heat Capacity - Heat Capacity And Calorimetry, Heat Capacity And The Law Of Conservation Of Energy - Significance of the high heat capacity of water. substance temperature cool raise. Heat capacity (often abbreviated Cp) is defined as the amount of heat required to raise the temperature of a given mass of a substance by one degree Celsius.
