The heat transfer process between a body and its ambient is governed by an internal conductive resistance $$\left( {{\rm I}CR} \right)$$ and an external convective resistance $$(ECR).$$ The body can be considered to be a lumped heat capacity system if
A
$${\rm I}CR > ECR$$
B
$${\rm I}CR$$ is marginally smaller than $$ECR$$
C
$${\rm I}CR = ECR$$
D
$${\rm I}CR$$ is negligible.
