What is this called?

That´s a well known Queen vs pawn on the 7th rank endgame.
It´s basically a win for white if the pawn is in columns b, d, e or g and black can draw with pawn in columns a, c, f and h.

I believe the king position is important too. For example I recently had a game with this situation where it would've a rook-file pawn on the 7th vs my queen, if we'd gone into that line, and it would've been a draw. However, if my king was one square closer in that position it would've been a win. Don't have time to post a diagram explaining it but it's something to consider.

Yes, the position of the king is important.
In the more basic endgame, when the white king is far from the action, the queen can only gain tempi with pawns on columns b, d, e or g. With that tempi white king comes closer and white wins.
When you have pawns on colums a, c, f and g it all depens on how far the white king is. If it is too far it is a draw.

I am unable to find it again but somewhere in chess.coms library is an example game.it goes like this. on one side of the board is a lone king,white for example.on the other side is a black king guarding, a pawn one move from queening. the while queen is also nearby.to avoid stalemate the white queen goes through a series of checks to separate the black king and pawn.
