Chromel specific heat
WebThe differential method is to place one end of the sample to be tested at a constant temperature and heat the other end at the average temperature of the sample Tave ( Tave = ( Tc + Ts )/2, where Tc = Tave − Δ T /2 and Ts = Tave + Δ T /2). A small temperature gradient Δ T is applied on the basis of Δ T. WebHeat capacity is the amount of heat required to change the temperature of a given amount of matter by 1°C. The heat capacity of 1 gram of a substance is called its specific heat capacity (or specific heat), while the heat capacity of 1 mole of a substance is called its molar heat capacity.
