Final answer:
A temperature indicator symbol on a flow chart indicates the temperature of a system, which is a measure of the average kinetic energy of molecules. Temperature affects a system's properties and behavior, and can be measured in scales like Fahrenheit, Celsius, and Kelvin.
Step-by-step explanation:
A temperature indicator symbol on a flow chart typically indicates the temperature of a system. In the context of fluid dynamics and thermodynamics, temperature is a fundamental quantity that can affect the behavior and properties of a system. For example, the boiling point of a liquid can be estimated by observing the temperature at different conditions, as reflected in a graph. Likewise, a constant-volume gas thermometer measures the temperature of a gas by monitoring a physical property that varies with temperature.The temperature is a measure of the average kinetic energy of molecules within a system and can be represented in different scales, such as Fahrenheit, Celsius, and Kelvin. These temperature scales have been devised to quantify the energy of motion in a system, and thermometers typically use substances that expand or contract with temperature changes to measure it. The ideal gas law, which is a fundamental equation in thermodynamics, relates the macroscopic pressure, temperature, and volume of an ideal gas, and can be expressed as PV = nRT (where P is pressure, V is volume, T is temperature, n is the number of moles, and R is the gas constant).
