Ce qui / ce que

Question

Are both of these sentences 
grammatically correct? I understand why 'ce qui' in the first sentence 
is correct, but not why 'ce que' would be correct in the second one. I 
would be grateful for an explanation.Ce qui à un moment donné est le substrat,
n’est pas chaud

Ce
que le substrat est à un moment donné, n’est pas chaud

Accepted Answer

Bonjour Jan !
Indeed here both sentences are correct, though they each take the statement from a different "end" so to speak :)1 -> What is at one point the substrate, isn't hot.
2 -> What the substrate is at one point, isn't hot.
I hope that's helpful!Bonne journée !
