Will water freeze if there is oil in the same container
colo high, australia
Sure. Just put it in the freezer. The oil may get more viscous and
sticky, or even harden up, although many oils don't really have just
one freezing temperature like the water does. The oil may act as a
thermal insulator, a blanket over the water, but that just makes the
freezing process take longer.
