The heating capacity of muffle furnace depends on the_________________?
Correct answer: C. Both A. & B.
- A. Surface area & emissivity of the stock
- B. Properties of the muffle wall (temperature, area, and emissivity)
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
A muffle furnace heats the charge indirectly, so heat transfer depends on both the charge surface and emissivity and the muffle wall's temperature, area, and emissivity. Hence both sets of properties affect heating capacity.
