1. When one walks barefoot from a carpet onto a ceramic tile floor, the tiles feel colderthan the carpet even though each surface is at the same temperature. Explain.
2. Air at 1 atm, 70°F in a closed tank adheres to the continuum hypothesis. Yet when sufficient air has been drawn from the tank, the hypothesis no longer applies to the remaining air. Why?
3. Are the systolic and diastolic pressures reported in blood pressure measurements absolute, gage, or vacuum pressures?
4. When the instrument panel of a car provides the outside air temperature, where is the temperature sensor located?
5. How does a pressure measurement of 14.7 psig differ from a pressure measurement of 14.7 psia?
6. What is a nanotube?
7. If a system is at steady state, does this mean intensive properties are uniform with position throughout the system or constant with time? Both uniform with position andconstant with time? Explain.
