1. Problem: Define temperature, absolute temperature scale corresponding to Fahrenheit, and convert 100° F to that scale. 2. Temperature is a measure of the average kinetic energy of particles in a substance. It indicates how hot or cold an object is. 3. The absolute temperature scale corresponding to Fahrenheit is the Rankine scale, defined as $$T_R = T_F + 459.67$$ where $T_F$ is temperature in Fahrenheit and $T_R$ is temperature in Rankine. 4. To convert 100° F to Rankine: $$T_R = 100 + 459.67 = 559.67$$ So, 100° F equals 559.67° R. 5. Final answers: - Temperature definition: measure of average kinetic energy. - Absolute temperature scale for Fahrenheit: Rankine scale. - 100° F in Rankine: 559.67° R.
