Heat Transfer

Q1: Pick out the wrong statement.

A Economy of a multiple effect evaporator is not influenced by the boiling point elevation.

B Two identical cubes of iron and copper will have the same heat content under the same conditions of temperature.

C Double pipe heat exchangers are mostly used in the field of refrigeration.

D Finned tube heat exchangers are suitable for heating air by steam.

ANS:B - Two identical cubes of iron and copper will have the same heat content under the same conditions of temperature.

The wrong statement is: "Two identical cubes of iron and copper will have the same heat content under the same conditions of temperature." This statement is incorrect because even though the cubes are identical in size and temperature, the heat content (or internal energy) of iron and copper will not be the same. This is because the specific heat capacity of iron and copper is different. Copper has a higher specific heat capacity compared to iron, meaning it requires more heat to raise its temperature by a certain amount. Therefore, the heat content of the copper cube will be higher than that of the iron cube under the same conditions of temperature.
