Hello everyone today. We are being asked to identify if the following processes are endo thermic or eggs are thermic and then to determine a phase transition. So the scenario is cooking oil solidifies during winter time solidifying. That should be a key word to let us know that we are going from a liquid to a solid and therefore that is known as freezing. So that is our phase transitions freezing. And then we know that since liquid is turning to solid, the bonds are what they're going to be forming. So we're going to say forming bonds in this situation, which means that eggs, a thermic an exit thermic reaction is occurring or energy known as heat. Energy is being released in the formation of these bonds. I hope this helped and until next time.
