1.	Thermal contact resistance can be affected by impact or thermal parameters during the casting process.(a) True(b) FalseI have been asked this question in homework.This is a very interesting question from Solidification with Constant Surface Temperature topic in portion Cooling and Solidification of Casting-Forming-Welding I
Answer» The correct answer is (B) False The explanation: The EFFECT of thermal contact resistance on the phase CHANGE process is very important to consider during solidification. Thermal contact resistance is VARIED by changing the heat transfer coefficient at the interface. Thermal contact resistance is always CONSTANT throughout the process and cannot be affected by impact or thermal parameters.
