Which of the following statements is true concerning the units of temperature. Hira_Kira. (A data logger can also measure humidity of an environment, pH of fluids etc) Measurement of Mass. The temperature of a system at thermodynamic equilibrium is defined by a relation between the amount of heat $ \delta Q $ incident on the system during an infinitesimal quasistatic process transformation, and the variation $ \delta S $ of its entropyduring this transformation. The units that are used to measure temperature are called degrees. Standard Units of Measurement. This answer has been confirmed as correct and helpful. 17. Temperature is the measure of heat in the body. The most common unit of speed is miles per hour (mph). In the United States, °F are used for surface measurements. The relative humidity is 50% and the air is unsaturated. The degree Celsius is a unit of temperature on the Celsius scale, a temperature scale originally known as the centigrade scale. Each person obtains a reading of exactly 7.32 g for the mass of the standard. 15.
