Question

Q 13. The coefficient of viscosity of
gas is
(A) independent of pressure and
O directly proportional to square root
of absolute temperature
(B) dependent of pressure and
O directly proportional to square root
of absolute temperature
(C) independent of pressure and
directly proportional to absolute
temperature
(D) independent of pressure and
O directly proportional forth power of
absolute temperature​

Answer 1

Answer:The viscosity of a gas can be thought of as a measure of its resistance to flow and is measured in the CGS unit Poise = dyne sec/cm2. The viscosity of gases near room temperature are in the centiPoise range, so that is a commonly used unit.The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 × 10-5 kg/(m·s) , 18.1 μPa·s or 1.81 × 10-5 Pa·s .
