The instrument used to determine the salt percentage in food is the Salinometer / Conductivity Meter.
A Salinometer measures the concentration of salt by determining the electrical conductivity of the solution, as salt increases conductivity. This instrument is commonly used in the food industry to ensure proper salt levels in processed food products.
Consider the following statements:
(A) Availability is generally conserved.
(B) Availability can neither be negative nor positive.
(C) Availability is the maximum theoretical work obtainable.
(D) Availability can be destroyed in irreversibility's.
