none of these.

[#]

Normality of a solution does not change with the increase in the

pressure

temperature

solute concentration

dilution of the solution

[#]

Highly viscous liquids & pastes are agitated by

propellers

multiple blade paddles

none of these

[#]

In case of a ball mill,

coarse feed requires a larger ball.

fine feed requires a larger ball.

operating speed should be more than the critical speed.

none of these

[#]

Screen capacity is not a function of

its openings size.

screening mechanism.

screening surface.

atmospheric humidity.

[#]

Natural convection is characterised by

Grashhoff number

Peclet number

Reynolds number

Prandtl number

[#]

[#]

On a P-V diagram of an ideal gas, suppose a reversible adiabatic line intersects a reversible isothermal line at point A. Then at a point A, the slope of the reversible adiabatic line (∂P/∂V)_s and the slope of the reversible isothermal line (∂P/∂V)_T are related as (where, y = C_p/C_v)

(∂P/∂V)_S = (∂P/∂V)_T

(∂P/∂V)_S = [(∂P/∂V)_T]^Y

(∂P/∂V)_S = y(∂P/∂V)_T

(∂P/∂V)_S = 1/y(∂P/∂V)_T
