If the temperature were increased from 273°K to 546°K, the minimum fluidization velocity of the gas would approximately:

(a) Increase by a factor of a) 1.4, b) 2.8, c) 2.0.
(b) Decrease by a factor of a) 1.4, b) 2.8, c) 2.0.
(c) Remain the same.
(d) Cannot be calculated from the information given.
(e) None of the above.

Assuming other variables (e.g. pressure, mole fractions,, particle size, etc.) remain virtually unchanged and the Reynolds number is less than 10.
