Thermistors

A thermistor is a special type of resistor whose resistance is more temperature-dependent than standard resistors. The resistance of the thermistor decreases with increasing temperature. This is the basic principle of thermistors. This allows the thermistor circuit to detect very small temperature changes that cannot be observed with the Resistance temperature detectors (RTDs) or the thermocouples. Since the resistance of a thermistor is temperature dependent, it can be connected to an electrical circuit to measure body temperature. This high sensitivity to temperature changes makes thermistors very useful for accurately controlling and calibrating temperature measurements. In general, resistance increases with increasing temperature in most metals, but thermistors react negatively.

Heat capacity Cv is the amount of heat required to raise the temperature of a given mass of gas with constant volume by 1 °c, measured in units of cal / deg-mol ( calories per degree gram molecular weight). The heat capacity of oxygen depends on its temperature T and satisfies the formulaCv = 8.27 + 10^-5 (26T - 1.87 T^2) Use Simpson's Rule to find the average value of Cv and the temperature at which it is attained for 20°c less or equal to T less or equal to 675°C.
