How is specific heat capacity measured
WebVIt = Mc P (θ 1 – θ o) + H. where VIt is the energy supplied to the heater in a time t, M is the mass of gas passing through in that time and H is the heat lost. As usual with continuous-flow experiments, by doing two measurements with the same temperature difference but with a different rate of flow H can be eliminated. Web8 apr. 2024 · According to the manufacturer, the accuracy of the device for thermal conductivity measurements was 5% of reading + 0.001 W/m K. Thermal diffusivity is derived by dividing conductivity with density whereas specific heat capacity describes how quickly a material reacts to a change in temperature.
