11.If the weight of a body immersed in a fluid exceeds the buoyant force, then the body will

rise until its weight equals the buoyant force

tend to move downward and it may finally sink

float

none of the above

12.The viscosity of a gas

decreases with increase in temperature

increases with increase in temperature

is independent of temperature

is independent of pressure for very high pressure intensities

13.A floating body is said to be in a state of stable equilibrium

when its metacentric height is zero

when the metacentre is above the centre of gravity

when the metacentre is below the centre of gravity

only when its centre of gravity is below its centre of buoyancy
