A. inversly
B. directly
C. fire resistance is not related to steam smootheness
D. none
Answer:A
Fire resistance is _________ proportional to smoothening of the steam.
A. inversly B. directly C. fire resistance is not related to steam smootheness D. none
Explanation: Fire resistance is directly proportional to smoothening of the steam. When there is no fire resistance there will be vigorous combustion taking place which will lead to improper production of steam. 6. Fire resistance of fluids is _______ to the vaporization of the fluid.
