__________________ of air does not increase with increase in temperature?
Correct answer: A. Density
- A. Density
- B. Thermal diffusivity
- C. Viscosity
- D. Thermal conductivity
Explanation
As temperature rises at approximately constant pressure, air expands and its density decreases. Gas viscosity, thermal conductivity, and usually thermal diffusivity increase over this range, so density is the exception.
