Suppose a 50-G Block of Silver (Specific Heat = 0

question 3

Multiple Choice

Suppose a 50-g block of silver (specific heat = 0.2350 J/g·°C) at 100°C is placed in contact with a 50-g block of iron (specific heat = 0.4494 J/g·°C) at 0°C, and the two blocks are insulated from the rest of the universe. The final temperature of the two blocks

• A) will be higher than 50°C.
• B) will be lower than 50°C.
• C) will be exactly 50°C.
• D) is unrelated to the composition of the blocks.
• E) cannot be predicted.

Definitions:

Average Fixed Cost

The fixed costs of production divided by the quantity of output produced; these costs decline as production increases.

Marginal Cost

The financial cost of producing an extra unit of a good or service.

Average Total Cost

The total cost of production divided by the quantity of output produced.

Average Variable Cost

Represents the cost that varies with the level of output, calculated by dividing the variable costs by the quantity produced.
