Following the same logic, when an object appears white, it virtually reflect all the EM waves coming Use the appropriate equations in your answer. Mass The three most commonly used temperature scales are the Fahrenheit . Which aspects of the competition formula are most advantageous? Temperature is defined in terms of the instrument we use to tell us how hot or cold an object is, based on a mechanism and scale invented by people. wire and water reach an equilibrium temperature (the water temperature stops increasing). The OpenStax name, OpenStax logo, OpenStax book covers, OpenStax CNX name, and OpenStax CNX logo To measure temperature, some scale must be used as a standard of measurement.
