This is a question in heat transfer? you can help me if u want thanks in advance.

1-Why is the semi-infinite solution applicable to any geometry at early times?

2-for one-dimensional, transient conduction, what is implied by the idealization of a semi-infinite solid? under what conditons may the idealization be applied to a plane wall?

3-how may a one term approximation be used to determine the transient thermal response of a plane wall, long cylinder, or sphere subjeccted to a sudden change in surface temperature?

4-what requirement must be satisfied for use of a one- term approximation to determine the transient thermal response of a plane wall, a long cylinder or a sphere experiencing one dimensional conduction due to a change in surface conditions? at what stage of a transient process is the requirement not satisfied?
