Use the Heat formula for both problems.
q=m*c*∆t
Where
q= heat in Joules
m= mass in grams
c= specific heat which is a constant 4.18
∆t= change in temperature

The problem here is that according to Aufbau Principle before 3d orbital 4s subshell comes.After filling 3p orbital with electrons you have 4 electrons left,you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with same spin.
Even though the process is endothermic, snow can sublime.
