During solidification, the interface temperature is independent to the magnitude of contact resistance.

(a) True

(b) False

I had been asked this question in unit test.

My doubt stems from Solidification with Constant Surface Temperature in portion Cooling and Solidification of Casting-Forming-Welding I

Right option is (a) True

The explanation: During solidification of casting material, the interface temperature which generally prevails in the absence of contact resistance has physical meaning when the contact resistance is in effect. The interface temperature is independent to the magnitude of contact resistance and is dependent only on the thermal properties.
