The Solutions in the Arms of a U-Tube Are Separated

question 41

Multiple Choice

The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl) , and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same. The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane.

Definitions:

Materials Price Variance

The difference between the actual cost of materials and the expected cost at standard prices.

Variable Overhead

Refers to the costs of production that fluctuate with the level of output, such as utilities and materials, that do not have a fixed price associated with production levels.

Direct Labor-hours

The total hours worked by employees directly involved in the production process, used as a basis for allocating costs to products.

Variable Manufacturing Overhead

Costs that vary with production output levels, such as utilities for the production facility, which are not directly tied to specific units of production.
