Question

Large compositional change occurs in the charge while using the Gas pit furnace.

(a) True

(b) False

The question was asked in homework.

My question is based upon Gas Fired Pit Furnace topic in chapter Melting Furnaces of Foundry and Forging

Answer 1

Correct choice is (a) True

To explain I would say: Since the molten metal does not come in contact with the fuel, there is no pick up of the elements by the metal from the coke and hence a very little compositional change occurs in the metal charge of the gas pit furnace.
